Hi, I do not understand well your problem. If you want to plot only the first 101 elements of eTrrr as a function of refsG you can simply use:

plot(refsG, eTrrr(1:101,2), ....)

Hi Annas Chand,

I guess transposing refsG or the matrix eTrrr should work. The dimensions don't match. I guess this is what causes the error.

Thank you Sir (Richard Epenoy & Andre Rieger), i will try it

Plot command in matlab works this way—> plot(x,y)

You are actually giving coordinates of a point in this command. so each point must have one X and one Y. This is why length of the two matrices which go for X and Y must be the same ...

Hope this would be helpful for you
