Constructor for CDC formatted data.

Assumes compressed and does not own memory.

Constructs a read-write Map to a sparse matrix of size rows x cols, containing nnz non-zero coefficients, stored as a sparse format as defined by the pointers outerIndexPtr, innerIndexPtr, and valuePtr. If the optional parameter innerNonZerosPtr is the null pointer, then a standard compressed format is assumed.

Parameters

rows	Number of rows
cols	Number of columns
nnz	Number of nonzero items in matrix
outerIndexPtr	A pointer to the array of outer indices.
innerIndexPtr	A pointer to the array of inner indices.
valuePtr	A pointer to the array of values.
innerNonZerosPtr	A pointer to the array of the number of non zeros of the inner vectors.
