Augustin M J

If you want to find the determinant of a matrix you can use symbolic objects in matlab

Please refer to http://www.mathworks.in/help/symbolic/sym.html

Ali Alrawi

you can use symbolic for example

syms x1 x2 x3 x4

>> A=[x1 x2;x3 x4]

A =

[ x1, x2]

[ x3, x4]

x1=9;x2=4;x3=2;x4=0;

xd=subs(A)

xd =

9 4

2 0
