Detailed Description

Represents a matrix of double-precision data.

Simple wrapper around an arbitrary pointer to the underlying data. The data is assumed to be stored in a contiguous block of memory. The data is interpreted column-wise, such that data[1] is element [1,0] of the matrix.

Initialization

A Matrix can be initialized a few ways. The easiest is via NewMatrix:

Matrix mat = slap_NewMatrix(rows, cols);

which allocates a new block of memory on the heap. It must be followed by a call to FreeMatrix().

If the data for the matrix is already stored in an array, the default brace initializer can be used:

double data[6] = {1,2,3,4,5,6};

Matrix mat = {2, 3, data};
