Hello!
I have a matrix with 250 columns and aprox 900,000 rows. where 250 are the channels, 900,000 is the time. I want to divide the rows into different trials of 150,000. Where the first dimension corresponds to the channels (250), the second dimension corresponds corresponds to time (150,000) and the third dimension corresponds to trials (6).
Thanks!

x = your 900000x250 matrix
xnew = reshape(x',250,150000,6);
