message "vectors with different lengths"

I am splitting my problem in five different sections. Each section has different equations. After solving the sections separately, I am trying to put the solutions together and plot the final solution.

You are trying to plot

plot(teta,s)

teta and s should be the same size, in your case, type

numel(teta)
numel(s)

you will get different sizes

I got it, but I would like to know how I can declare a vector with zeros and size one hundred

[Azzi Abdelmalek]

v=zeros(1,100)
