Hi,
I want to plot Out (length 777) and time (length 389) and error appears 'Vector must be of same length'. So I need to regularize time (want make time of same length of Out). How can I regularize time in MATLAB to get vector (time) af same length.

plot(linspace(min(time), max(time), numel(Out)), Out)

When I try this code plot(linspace(min(time), max(time), numel(Out)), Out)
same error appears. Vectors must be of same length.

Indeed, if the first 12 elements are NaNs, the min(time) part of Madhan's code will not return 1, but rather 13 as an output. Then the variables still have different sizes.
You can solve this with the size function instead.
out = randn(1,777); %e.g. data
time = 1:389;
plot( linspace(size(time,1), size(time,2), length(out) ), out)
