evaluate

public OperandToken evaluate(Token[] operands,
                             GlobalValues globals)
return a sub matrix and assign a submatrix

Specified by:
evaluate in class Function
Parameters:
operands[0] - = original matrix
operands[1] - = replacement matrix
operands[1] - = vertical limits (1 or 1:3 or : )
operands[2] - = horizontal limits (optional) (1 or 1:3 or : ) (e.g.: a= subassign(a,b,1,1) assigns the value b to the element (1,1) of matrix a, a = subassign(a,b,:,2) assigns b as the second column of a, a = subassign(a,b,2:3,0:2) assigns b as a 2-by-3 submatrix of a, a = subassign(a,b,2) returns the first element of the second row of a
Returns:
the result as an OperandToken
