Requested 196608x4096 (12.0GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and cause MATLAB to unresponsive

I have two matrices.

Matrix A : size is 196608x4096 sparse double

Matrix B: size is [ 16 16 16 ] double

I was trying to multiply them through a loop ( As I have other operations to execute)

Inside the loop , when these two matrices are multiplied at that moment I am getting the error :

"Requested 196608x4096 (12.0GB) array exceeds maximum array size preference. Creation of arrays greater

than this limit may take a long time and cause MATLAB to become unresponsive."

I tried with "tall" but sparse matrix cannot be converted into tall . I there any way to tackle this problem as I do not have large amount of memory in my laptop.

Thanks in Advance.
