<H4>Routine</H4>
<DL>
<DT>
double **MAdAllocMat (int Nrow, int Ncol)
</DL>
<H4>Purpose</H4>
<DL>
<DT>
Allocate a matrix of double values
</DL>
<H4>Description</H4>
This routine allocates a matrix of double values. The returned value is
a pointer to an array of pointers to the rows of the matrix. The calling
routine can treat the returned value as a two-dimensional matrix of double
values. Consider the invocation
<PRE>
double **A;
int Nrow, Ncol;
...
A = MAdAllocMat (Nrow, Ncol);
</PRE>
Then A[i][j] is a matrix of double values for 0 <= i < Nrow and
0 <= j < Ncol. The routine MAdAllocMat allocates an array of Nrow pointers
and a contiguous block of memory sufficient to hold the Nrow*Ncol double
values. Each pointer is initialized to point to a row of the matrix. A[0]
is a pointer to the first row (Ncol double values) (and to the full matrix of
Nrow*Ncol double values). A[1] points to the next row (Ncol elements beyond
A[0]), and so on.
<P>
The space allocated by this routine should be deallocated using the routine
MAdFreeMat.
<H4>Parameters</H4>
<DL>
<DT>
<- double **MAdAllocMat
<DD>
Returned pointer to array of row pointers
<DT>
-> int Nrow
<DD>
Number of rows for the matrix
<DT>
-> int Ncol
<DD>
Number of elements in each row (number of columns)
