Create sprase matrix from data on host memory

This function converts host array values into sparse array of format sparse format using host arrays row_indices and col_indices.

Parameters

• rows is the number of rows in the dense matrix
• cols is the number of columns in the dense matrix
• nzz is the number of non zero elements in the dense matrix
• values is the \ref af::array containing the non-zero elements `of the matrix
• row_indices is the row indices for the sparse array
• col_indices is the column indices for the sparse array
• format is the storage format of the sparse array

Return Values

Array with data in given sparse format

Note

The rules for deep copy/shallow copy/reference are the same as for creating a regular Array.
