Detailed Description

Matrix type that contains the elements of float type.

Actually, This is a typedefed type by typedef struct _spFMatrix *spFMatrix;. To allocate memory for spFMatrix, call a function with prefix xfm such as xfmalloc() , xfmzeros() , etc. To deallocate memory, call xfmfree() .

Field Documentation

row

long row

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

col

long col

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

data

float** data

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

imag

float** imag

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