rhs
Right side (RHS) of equation
Syntax
Description
Examples
Find Right Side of Equation
Find the right side of the equation 2*y
== x^2
by using rhs
.
First, declare the equation.
syms x y eqn = 2*y == x^2
eqn = 2*y == x^2
Find the right side of eqn
by using rhs
.
rhsEqn = rhs(eqn)
rhsEqn = x^2
Find Right Side of Condition
Find the right side of the condition x
< y + 1
by using rhs
.
First, declare the condition.
syms x y cond = x < y + 1
cond = x < y + 1
Find the right side of cond
by using rhs
.
rhsCond = rhs(cond)
rhsCond = y + 1
Note
Conditions that use the >
operator are
internally rewritten using the <
operator. Therefore, rhs
returns
the original left side. For example, rhs(x > a)
returns x
.
Find Right Side of Equations in Array
For an array that contains equations and conditions, rhs
returns
an array of the right sides of those equations or conditions. The
output array is the same size as the input array.
Find the right side of the equations and conditions in the vector V
.
syms x y V = [y^2 == x^2, x ~= 0, x*y >= 1]
V = [ y^2 == x^2, x ~= 0, 1 <= x*y]
rhsV = rhs(V)
rhsV = [ x^2, 0, x*y]
Because any condition using the >=
operator
is internally rewritten using the <=
operator,
the sides of the last condition in V
are exchanged.
