[Tex/LaTex] How to wrap text around a matrix

matriceswrapfigure

In the middle of a paragraph (text is justified), I have a 5-row matrix. I've been trying to find a way to wrap the text in the paragraph around the matrix, so there aren't large gaps above and below the text on that line. I have heard of the wrapfig package, but haven't managed to get this to work yet.
Below is a sample similar to the code I have so far (I switched from using an array environment to tabular after discovering I may be able to use \begin{wraptable}):

`This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$. $L =  \left[ \begin{tabular}{ccccc}
                $F_1$&$F_2$&$\cdots$&$F_{d-1}$&$F_d$ \\
                $P_1$&$0$&$\cdots$&$0$&$0$ \\
                $0$&$P_2$&$0$&$\cdots$&$0$ \\
                $\vdots$&$\ddots$&$\ddots$&$\ddots$&$\vdots$ \\
                $0$&$\cdots$&$0$&$P_{d-1}$&$0$
                \end{tabular} \right].$ This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$. This is a paragraph containing random text which I want to wrap around the matrix $L$.`

Thank you in advance!

You can use wrapfigure from wrapfig package.

\documentclass{article}
\usepackage{amsmath}
\usepackage{wrapfig}
\begin{document}

       \begin{wrapfigure}[8]{r}[0pt]{6cm}
     \raggedleft $L =  \left[ \begin{array}{ccccc}
                F_1    & F_2    & \cdots & F_{d-1} & F_d    \\
                P_1    & 0      & \cdots & 0       & 0      \\
                0      & P_2    & 0      & \cdots  & 0      \\

                0      & \cdots & 0      & P_{d-1} & 0      
                \end{array} \right].$
\end{wrapfigure}

By the way, you can use an array instead of that nasty tabular

Don't

use capital letters (like R) for float specifiers. Capital letters mean the figure can float.
don't use a group to wrap the wrapfigure environment.

Do

put sufficient text in the paragraph following wrapfigure.
specify the number of lines to be cut (so as to accomodate wrapfigure) as tols by olga.saucedo.

Here is the commented code.

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage[margin={2.2cm}]{geometry}%
\usepackage{wrapfig, blindtext}

\begin{document}
\section{The problem}
\begin{wrapfigure}[12]{r}{0.3\textwidth}
\centering
\rule{0.9\linewidth}{0.75\linewidth}
\caption{\label{fig:d1}Integrating a function}
\end{wrapfigure}

We can always approximate the area by dividing it in equal width strips and
then sum the areas of all the strips.

enter image description here

In general, there will always be an error in the estimate of the area using
this method. The error will become smaller the more strips
we use (which implies a smaller strip width). Hence we can write%

\[
{\displaystyle\int\limits_{a}^{b}}
f\left(  x\right)  \ dx=\left(
{\displaystyle\sum\limits_{i=1}^{N}}
\Delta x\ f\left(  x_{i}\right)  \right)  +E
\]

Where $E$ is the error between the actual area and the approximated area using the
above method of numerical integration. $N$ above is the number of strips or
can also be refereed to as the number of integration points.

Instead of keep referring to the 'width of the strip' all the time, we will
call this quantity the weight $w_{i}$ that we will multiply the value of the
function with to obtain the area. Hence the above becomes

\[%
{\displaystyle\int\limits_{a}^{b}}
f\left(  x\right)  \ dx=\left(
{\displaystyle\sum\limits_{i=1}^{N}}
w_{i}\ f\left(  x_{i}\right)  \right)  +E
\]

Using implied summation on indices the above becomes

\[%
{\displaystyle\int\limits_{a}^{b}}
f\left(  x\right)  \ dx=w_{i}\ f\left(  x_{i}\right)  +E
\]

In the above we divided the range of the integration (the distance between the
upper and lower limits of integration) into equal intervals. We can decide to
evaluate $f(x_{i})$ at the middle of the strip or at the start
of the strip or at the end of the strip. In the diagram above we evaluated the
$f(x)$ at the left end of the strip.

Our goal is to evaluate this integral such as the error $E$ is minimum and using
the smallest number of integration points. In a sense this can be considered
an optimization problem with constraints: minimize the error of integration
using the smallest possible number of points.

Wrapping something should be in a paragraph. Hence critical part of your file should be (corrected in your file now):

\lipsum
\begin{wrapfigure}{l}{.525\textwidth} %this figure will be at the right
    \includegraphics[width=.525\textwidth]{T vs R - tungsten filament.png}
    \begin{center}
Figure 3
\end{center}
\end{wrapfigure}

%\lipsum

(Observe the position of `\lipsum).

BTW: Replacing all text \\'s by blank lines would help (La)TeX to correct dividing paragraphs into lines.

Edit New version:

$\,$
\begin{wrapfigure}{l}{.525\textwidth} %this figure will be at the right
    \includegraphics[width=.525\textwidth]{T vs R - tungsten filament.png}
    \begin{center}
Figure 3
\end{center}
\end{wrapfigure}

\lipsum
