Hello guys,
I have a function in a for loop and I want to get different values for different timestamps. In order to plot the results, I need the values from the for loop. The function fy gives me a [4,1] matrix and all I want is a "result" matrix with all values from the loop. I know that the dimensions do not fit, but I can't come up with a solution. Thanks for helping!
CODE
fy = @(t) (V*expm(D.*t)*inv(V))*x0;
for i = 1:20
y(i) = fy(i);
end
ERROR
Unable to perform assignment because the indices on the left side are not compatible with the size of the right side.

for i = 1:20
y(:,i) = fy(i);
end

You can insert the returned values in colums. For example
fy = @(t) (V*expm(D.*t)*inv(V))*x0;
y = zeros(4, 20);
for i = 1:20
y(:, i) = fy(i);
end
