Hi all,

I have a matrix of 251*27 dimension, that I want to store it in the new 3d one that has a dimension of 251*27*10. it means that each third dimension of the 10th should have 251*27. the command that I use which is not correct is :

 the dim of geov is (251,27);
gridpav = nan(size(geov));
for i = 1:10 
    gridpav (:,:,i) = pav(i);
end

thanks for the help.

sorry but i have another question if that possible, i am also using the previous command to apply pcolor for the data. which means having individual plots from 1 to 10 with the data of x-axis: gridlonv, y-axis: gridpav, colored data: geov

for example transect numbe 5:

pcolor(gridlonv(:,:,5),-gridpav (:,:,5),geov(:,:,5))

but the figure shows nothing!

thanks again for the help.
