Detailed Description

Matrix type that contains the elements of double type.

Actually, This is a typedefed type by typedef struct _spDMatrix *spDMatrix;. To allocate memory for spDMatrix, call a function with prefix xdm such as xdmalloc() , xdmzeros() , etc. To deallocate memory, call xdmfree() .

Examples: mattest.c.

Field Documentation

◆ row

long row

The number of rows of spDMatrix. You can access the number of elements as x->row for the memory allocated x of spDMatrix.

Examples: mattest.c.

◆ col

long col

The number of columns of spDMatrix. You can access the number of elements as x->col for the memory allocated x of spDMatrix.

Examples: mattest.c.

◆ data

double** data

Data of the real part of spDMatrix. You can access the element of the data at row 0, column 0 as x->data[0][0] for the memory allocated x of spDMatrix.

Examples: mattest.c.

◆ imag

double** imag

Data of the imaginary part of spDMatrix. You can access the element of the data at row 0, column 0 as x->imag[0][0] for the memory allocated x of spDMatrix. If no imaginary part exists, this member can be NULL.

Examples: mattest.c.
