Hi, I have a data acquired from ECG sensor sampled at 128 sps I want to make subarrays each contains 256 sample?

sps = 128;
n = 768; % 128*6 = 768, so a 6s long signal with 128 sps
x = randn(1,n);
y = reshape(x, [], sps*2);

It should be indeed
reshape(x, [], 50)
to divide the data into 50 columns or even better:
reshape(x, 256, [])
to split the data into columns of 256 elements. In each case, each subarray ends up as a column.
