rref
CAS: Reduce a matrix to row-reduced echelon form, and provide a list of pivot points.
RREF
CAS: Reduce a matrix to row-reduced echelon form – the reduction is carried out completely, so a
square matrix is reduced to an identity matrix. Step-by-step mode can be used to show how the
reduction proceeds.
RREFMOD
CAS: Perform modular row-reduction to echelon form on a matrix, modulo the current modulus.
RRK
Type: Command
Description: Solve for Initial Values (Rosenbrock, Runge–Kutta) Command: Computes the solution to an
initial value problem for a differential equation with known partial derivatives.
RRK solves y
'(t) = f(t,y), where y(t
0
) = y
0
. The arguments and results are as follows:
• { list } contains five items in this order:
– The independent variable (t).
– The solution variable (y).
– The right-hand side of the differential equation (or a variable where the expression is
stored).
– The partial derivative of y'(t) with respect to the solution variable (or a variable where the
expression is stored).
