[Scilab-users] How to solve a matricial equation in scilab

[CRETE Denis]

Your equation is [AB,C2]*[C1,CD]  = R, where AB =[a ; b], CD=[c ; d], C1=[3;-2] and C2=[2;4] and R=[5 7;-5 9].
AB=(R(:,1)-C1(2)*C2)/C1(1);
CD=inv([AB,C2])*R(:,2);
It appears that there is a solution if det([R(:,1),C2]) ~= 0

And what about an equation like

[a 2; b 4] * [3 c; -2 d] = [5 7;-5 9]
