The matrix functions defined in the
Table 4-5. In most of the function prototypes:
is a pointer to input matrix
*a
is a pointer to input matrix
*b
is an input scalar
b
is the number of rows
n
is the number of columns
m
is a pointer to output matrix
*c
In the
matrix*matrix
and and are the dimensions of matrix
k m
The functions described by this header assume that input array arguments
are constant; that is, their contents do not change during the course of the
routine. In particular, this means the input arguments do not overlap with
any output argument.
