vldiv, vpinv, vrdiv (Mu Analysis and Synthesis Toolbox)

Mu Analysis and Synthesis Toolbox

vldiv, vpinv, vrdiv

Determine left division, pseudo-inverse and right division of a CONSTANT or VARYING matrix

Syntax

out = vldiv(mat1,mat2) 
out = vpinv(mat,tol) 
out = vrdiv(mat1,mat2)

Description
These commands operate on VARYING matrices and they are identical to the MATLAB commands \, pinv, and / on CONSTANT matrices.

vldiv of a VARYING matrix returns out, which is a VARYING matrix, containing the value of the left division (mat1(i)mat2(i)) at each independent variable value. vldiv is identical to the MATLAB command \ for CONSTANT matrices.

vpinv of a VARYING matrix returns out, which is the pseudo-inverse of mat at each independent variable. out is of the same dimension as vcjt(out), and satisfies mat = mmult(mat,out,mat). tol is used within the svd routine to determine zero singular values. The default value of tol is 1e-12. vpinv is identical to the MATLAB command pinv for CONSTANT matrices.

vrdiv of a VARYING matrix returns out, which is a VARYING matrix, containing the value of the right division (mat1(i)/mat2(i)) at each independent variable value. vrdiv is identical to the MATLAB command / for CONSTANT matrices.
