evaluate

public OperandToken evaluate(Token[] operands,

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
