rref Reduces a matrix to row-reduced echelon form and
returns pivot points.*
RREF Reduces a matrix to row-reduced echelon form.*
RREFMOD Performs modular row-reduction to echelon form on a
matrix, modulo the current modulus.
RRK Computes the solution to an initial value problem for a
differential equation with known partial derivatives.
RRKSTEP Computes the next solution step to an initial value problem
for a differential equation, and displays method used.
Returns an error estimate for a given step h when solving
RSBERR
an initial values problem for a differential equation.
RSD Computes the residual B – AZ of the arrays B, A, and Z.
RSWP Swaps rows i and j of a matrix and returns the modified
matrix.
R→B Converts a positive real to its binary integer equivalent.
R→C Combines two real numbers or real arrays into a single
complex number or complex array.
R→D Converts a real number expressed in radians to its
equivalent in degrees.*
