MATLAB: Generating sequences from data

generating sequences from data

Hi All,

I have a data set (x1, x2, x3, x4, x5, x6, x7, …. xn) from which I want to generate sequences like

x1, x2, x3, x4, x5

x2, x3, x4, x5, x6

x3, x4, x5, x6, x7

x4, x5, x6, x7, x8

………………… xn

Thank you

xy = [5    14
     6    16
     1    16
     6    11
     4    16
     1    16
     2    13];
n = 5;
[m,k] = size(xy);
out = xy(reshape(hankel(1:n,n:m),1,n,[]) + m*(0:k-1)')

MATLAB: I wrote this code and got this error (The function “FinalCost” was closed with an ‘end’, but at least one other function definition was not. To avoid confusion when using nested functions, it is illegal to use both conventions in the same file.)

When you call FinalCost here:

    %calling finalCost to calculate the finalcost and the optimal values

    %for x and y for the wharehouse

    function [Cost, x, y] = FinalCost(x1, x2, x3, x4, x5, x6, y1, y2, y3, y4, y5, y6, v1, v2, v3, v4, v5, v6);

instead use

        %calling finalCost to calculate the finalcost and the optimal values
    %for x and y for the wharehouse
    [Cost, x, y] = FinalCost(x1, x2, x3, x4, x5, x6, y1, y2, y3, y4, y5, y6, v1, v2, v3, v4, v5, v6);

Otherwise, MATLAB thinks you are defining the function rather than calling it.

MATLAB: How to create many different plots, on different figures, quickly and neatly

The first mistake was creating variable names like this: x, x2, x3. Such variable names make it extremely difficult to write compact code and are discouraged: https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval. It is better to create a cell array, and then you could easily use for-loop. For example, now you can do something like this

X = {x, x2, x3, x4, x5, x6, x7, x8, x9, x10};
Y = {y, y2, y3, y4, y5, y6, y7, y8, y9, y10};
for i = 1:numel(X)
    figure(i)
    plot(X{i}, Y{i})
end
