hi,

for s=1:500

consall1(s,:,:)=[cons1, cons2, cons31, cons32, cons33, cons34];

end

from above mentioned for loop.I need a single matrix with 6 rows.please reply with your ideas.

my cons1....cons34 changes in loop so after every iteration i have different consall1..i want to combine them with 500 rows 6 coloms..soryy for not explaining clearly

So besides the needless introduction of a third dimension, what is wrong with your code fragment? I assume that you cannot vectorize the calculation of cons1,...34. To speed up a bit (though it won't make a big difference here), you can preallocate consall1 with

consall1=zeros(500,6);

and then start overwriting the zeros with the values in the loop.
