Removing NaN row from matrix

Hi, i have a huge time series where the whole first vertical row is NaN. I'm totally new to Matlab but i need to erase the whole row or convert all NaN to 0. If anyone can give me a step by step guide for dummies on how to do this it would be much appreciated.

Audun - by vertical row do you mean a column? If you want to remove the first column from your matrix, then you could do something like

 A = randi(255,4,5);  % test matrix with four rows and five columns
 A = A(:,2:end);      % remove the first column of A

Else you can use isnan to find those NaNs in your matrix and set to zero.

 A = randi(255,4,5);
 A(:,1) = NaN;
 A(isnan(A)) = 0;

Yes, by "vertical row i mean column". I have some questions: 1. Where does the number 255 come in? 2. Do i run this in the live script?

Peder - the A matrix is just an example. I use randi to generate a 4x5 matrix of integers from 1 to 255. Your matrix would be named and populated in some other manner...
