MATLAB Function Reference |

Measure performance using stopwatch timer

**Syntax**

**Description**

```
toc
```

prints the elapsed time since `tic`

was used.

```
t = toc
```

returns the elapsed time in `t`

.

**Remarks**

The `tic`

and `toc`

functions work together to measure elapsed time. `tic`

saves the current time that `toc`

uses later to measure the elapsed time. The sequence of commands

measures the amount of time MATLAB takes to complete one or more `operations`

, and displays the time in seconds.

**Examples**

This example measures how the time required to solve a linear system varies with the order of a matrix.
