# `rhs`

Right side of equations, inequalities, relations, intervals, ranges and tables

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

## Syntax

```rhs(`f`)
```

## Description

`rhs(f)` returns the right side of `f`.

The call `rhs(f)` is equivalent to the direct call `op(f,2)`, of the operand function `op`, if `f` is not a table.

If `t` is a table, the call `rhs(t)` returns the list of values of the table (right side). Note that the `i`th value in `rhs(t)` corresponds to the `i`th key in `lhs(t)`.

## Examples

### Example 1

Extract the right sides of various objects:

`rhs(a <= b), rhs(m-1..n+1)`

The operands of an expression depend on its internal representation. In particular, a “greater” relation is always converted to the corresponding “less” relation:

```y > -infinity; rhs(y > -infinity)```

```y >= 4; rhs(y >= 4)```

### Example 2

Extract the right sides of the solution of the following system:

`s := solve({x + y = 1, 2*x - 3*y = 2})`

`map(op(s), rhs)`

Calls to `rhs` can be easier to read than the equivalent calls to the operand function `op`:

`map(op(s), op, 2)`

However, direct calls to `op` must be preferred inside procedures for higher efficiency.

`delete s:`

### Example 3

Extract the keys (left side) and values (right side) from a table:

```t := table(1=2, 4=PI, 5=5.6, 19=1/2): l := lhs(t);```

`r := rhs(t);`

Note that the `i`th value corresponds to the `i`th key:

`bool(r = map(lhs(t), e->t[e]))`

`delete t,l,r:`

## Parameters

 `f` An equation `x = y`, an inequality ```x <> y```, a relation `x < y`, a relation ```x <= y```, an “is element of”-relation ```x in y```, an interval `x...y`, a range `x..y`, or a table `table(x=y,...)`

`f`
