Detailed Description

This class represent the 4x4 matrix.

Operators

This class supports the following operators:

Member Operation Syntax Description Example
__add__ Addition a + b Adds values on either side of the operator. a + b = 30
__sub__ Subtraction a - b Subtracts right hand operand from left hand operand. a – b = -10
__mul__ Multiplication a * b Multiplies values on either side of the operator. a * b = 200
__truediv__ Division a / b Divides left hand operand by right hand operand. b / a = 2
__neg__ Negation -a Return the value negated. a = -b
__eq__ Equality a == b If the values of two operands are equal, then the condition becomes true. (a == b) is not true.
__ne__ Difference a != b If values of two operands are not equal, then condition becomes true. (a != b) is true.
__gt__ Greater Than a > b If the value of left operand is greater than the value of right operand, then condition becomes true. (a > b) is not true.
__lt__ Less Than a < b If the value of left operand is less than the value of right operand, then condition becomes true. (a < b) is true.
__ge__ Greater Than or Equal a >= b If the value of left operand is greater than or equal to the value of right operand, then condition becomes true. (a >= b) is not true.
__le__ Less or Equal a <= b If the value of left operand is less than or equal to the value of right operand, then condition becomes true. (a <= b) is true.
__iadd__ Addition (Inplace) a += b It adds right operand to the left operand and assign the result to left operand. c += a is equivalent to c = c + a
__isub__ Subtraction (Inplace) a -= b It subtracts right operand from the left operand and assign the result to left operand. c -= a is equivalent to c = c - a
__imul__ Multiply (Inplace) a *= b It multiplies right operand with the left operand and assign the result to left operand. c *= a is equivalent to c = c * a
__itruediv__ Divide (Inplace) a /= b It divides left operand with the right operand and assign the result to left operand. c /= a is equivalent to c = c / ac /= a is equivalent to c = c / a
