# MATLAB

Matlab is a commercial numerical computing language which costs $149.

Students are usually forced to use it in introductory math classes.

Unless required to use Matlab, I recommend using Python, Julia, or R which are all free and, in my opinion, more flexable.

For optimal CPU performance, you can also use C++ with Eigen.

## Usage

### Anonymous Functions

```
sqr = @(x) x.^2;
```

### Timing Code

Reference

`tic`

starts a timer. `toc`

returns the time elapsed in seconds since the started timer.

```
timerVal = tic
% The program section to time.
elapsedTime = toc(timerVal)
```
