Detailed Description

Matrix type that contains the elements of long type.

Actually, This is a typedefed type by typedef struct _spLMatrix *spLMatrix;. To allocate memory for spLMatrix, call a function with prefix xlm such as xlmalloc() , xlmzeros() , etc. To deallocate memory, call xlmfree() .

Field Documentation

row

long row

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

col

long col

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

data

long** data

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

imag

long** imag

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