Hi there,

I am using symbolic array but come across a transpose error. Below is the code:

    syms x1 x2 x3
    cstr = [6*x1^2 + 3*x2^2 - 2*x2*x3 + 3*x3^2 -17*x1 + 8*x2 -14*x3 + 19, ... 
            5 - x1 - 2*x2 -x3, ...
            7 - 5*x2 - 3*x3, ...
            x1*(2 - x1), ...
            x2*(2 - x2)];

However, after transposing the array, it becomes:

    cstr =
 6*x1^2 + 3*x2^2 - 2*x2*x3 + 3*x3^2
                       8*x2 - 17*x1
                         19 - 14*x3
                      5 - 2*x2 - x1
                                -x3
                    7 - 3*x3 - 5*x2
                       -x1*(x1 - 2)
                       -x2*(x2 - 2)

How can I make correct transposition.

and

cstr.'

will give you what you want.
