MATLAB: Plot vectors from the origin

linear algebraplotting

I am learning matlab and trying to plot vectors. I defined V=[3;4] to represent 3x^+4y^ and attempt to display using plot(V) hoping to see a vector from origin to (3,4) but instead the graph shows a vector from (1,3) to (2,4). Is it a problem with my plotting settings or am I not using the correct script?

Best Answer

plot([0 3], [0,4])
%    x1 x2, y1 y2
% or
quiver(0, 0, 3, 4)
%     x1 y1 x2 y2

MATLAB: Shifting origin

I actually did this finally. I scan the image left-to-right and top-to-bottom and stop the moment I find a different pixel than the background. Since I am using im2bw(); the background is white and the character pixel are black.

The moment I find the first black pixel, I store the pixel co-ordinates in 2 variables fr and fc. I then use these variables for further computation (i.e. constructing the grid)

MATLAB: Plot a line, changing origin

Hi!

x = [1 2 3];
y = [2 4 9];
plot(x,y);

This doesn't start at (0,0). If you have problems please post your code.
