Choose a parallel computing solution

Parallel computing can help you to solve big computing problems
in different ways. MATLAB^{®} and Parallel Computing Toolbox™ provide
an interactive programming environment to help tackle your computing
tasks. If your code runs too slowly, you can profile it, vectorize
it, and use built-in MATLAB parallel computing support. Then
you can try to accelerate your code by using `parfor`

on
multiple MATLAB workers in a parallel pool. If you have big data,
you can scale up using distributed arrays or `datastore`

.
You can also execute a task without waiting for it to complete, using `parfeval`

,
so that you can carry on with other tasks. You can use different types
of hardware to solve your parallel computing problems, including desktop
computers, GPUs, clusters, and clouds.
