Structure Consisting of the Fields

A MATLAB can also solve the sets of equations. In this illustration, the solutions for x, y, & z are returned as a structure consisting of the fields for x, y, & z. The separate solutions are symbolic expressions stored in the fields of structure.

>> solve('4*x-2*y + z=7' , 'x+ y+ 5*z=10' , '-2*x+ 3*y-z=2')

ans =

       x: [1x1  sym]

       y: [1x1  sym]

       z: [1x1  sym]

To refer to the separate solutions, that are in the structure fields, the dot operator is used.

>> x = ans.x

x =

124/41

>> y = ans.y

y =

121/41

>> z = ans.z

z =

33/41

The double function can therefore be used to convert the symbolic expressions to numbers, and store the outcomes from the three unknowns in a vector.

>> double([x y z])

ans =

       3.0244   2.9512   0.8049
