Generate a matrix.

Parameters:

  • rows (Constant) – The number of rows.

  • cols (Constant) – The number of cols.

  • columnsCapacity (Constant) – The amount of memory (in terms of the number of columns) allocated to the matrix. When the number of columns exceeds columnsCapacity, the system will first allocate memory of 1.2~2 times of capacity, copy the data to the new memory space, and release the original memory.
