dispmat_see

Parameters

A :

a n-by-m matrix of doubles

Description

Create a graphics with 4 subplots. Print A with

• a mesh,
• the pseudo-inverse of A as a mesh,
• the svd of A in log scale,
• the real and imaginary parts of the eigenvalues.

Examples

A=[ -9 11 -21 63 -252 70 -69 141 -421 1684 -575 575 -1149 3451 -13801 3891 -3891 7782 -23345 93365 1024 -1024 2048 -6144 24572 ]; h = dispmat_see ( A ); // Take some time to see the matrix... // ... now close close ( h );
