Hello,
I have a column of data with several rows (about 125000).
I want to copy that data, every 62 rows, to separate columns. So I would have from row 1 to 62 in column A, from row 63 to 125 in column B, from row 126 to 188 in column C and so on until there is no more data.
Is there an easy way to do this? Thank you so much in advance! (I'm new in matlab)

a=rand(12500,1); % Example
n=numel(a);
ii=mod(-n,62),
a(end+1:end+ii)=nan
out=reshape(a,62,[])

You probably want the reshape() function.
doc reshape
for syntax details.

As mentioned, you need to reshape the matrix, but for your data size, which is 125000, since it's not a multiply of 62 you need to pad it with (54) zeros and then reshape it
roughly it's gonna be like
data(1,end:end+54) = 0; % adds 54 zeros to the end of data to be multiply of 62
reshape(data,[],62);
I didn't check the code, might have minor problems ;)
