Re: error in 'solve' --> not a valid expression or equation
Of course in my original post it was meant to be: lambda = [lambda11 lambda12; lambda21 lambda22] Looking forward to your sugge...

error in 'solve' --> not a valid expression or equation
Hi, I defined three symbolic 2x2 matrices: lambda, beta and sigma: lambda = [lambda11 lambda12 lambda21 lambda22]; beta = [b11 b...
