x = linsolve(A,b,opt)
Inputs
- A
 - The left-hand side matrix.
 - b
 - The right-hand side vector or matrix.
 - opt
 - Options argument. See Comments.
 
Outputs

 - The solution vector or matrix.
 
Example
Positive definite example.
a=[3,1;1,3];
b=[1;2];
opt = struct('POSDEF', {true});
x=linsolve(a,b,opt)
      x = [Matrix] 2 x 1
