How can I assign values to my whole cell array? I am getting [], but am unsure as to why.

I want my code to assign epochs (in 'a' datapoint intervals) into a cell array. In this case 'a' is 200. Total recording length is 587 epochs. 'k' is my patient number. Therefore, in this use case I should have a cell array with 46x587 cells, where each cell contains a 21x200 double. My code can be seen below:
for k = 1:46
for i = 1:b
NC_x{k, i} = NC_patient{k}(:,a*(i-1)+1:a);
end
end
Unfortunately, only the first column of my cell array is assigned the 21x200 doubles. Why is this, and how can I resolve it?
I look forward to receiving a response.
Kindest regards,
Sean

It's a bit difficult to know what the problem is. You don't mention what the value of b is. Could it be 1, and therefore you are only operating on the first column, in the loop over i?
Can you upload the data in a MAT file, so we can run your code?

Assume b is greater than 1. In this instance it is 587. The code is pretty long, this is just one section of it. I was just wondering if there was any obvious reason why variables past the first column aren't being assigned cells.
