How to find the commands that I need in matlab?

Matlab has many useful functions for many different things. It's impossible know the name of each function. Most of the time I know what the function I need must do but I don't know the name of that function into Matlab. Then I can't have help of the help options of the Matlab. So many times I need internet for search the name of the matlab function name.

I would like know a function, like help | findstr /i <string> of cmd or apropos <string> of Scilab and bash terminals, for search a string through local documentation into the matlab.

In MATLAB help, open the "Functions" document. I guess there all of the functions are explained with one sentence.

If your issue is searching through the documentation without internet, you can use Help Browser (shown in the figure) which can be opened by entering doc in the command window. You can search any string through your location documentation using it.

Help Browser

If you use already know the name of the function and want to read its documentation, you can directly use: doc (function name) e.g. doc sum, it will open the documentation of the sum function.

You can use lookfor to search the local documentation. This will search the documentation of both built-ins as well as any user-defined functions that are on your path.

By default, it will search only the first line of the documentation for each function/class.

lookfor(searchString)

If you want to search the entire help comment block, you'll want to use the -all flag

lookfor(searchString, '-all')

If your search string is only a single word, you can use the command syntax instead

lookfor <search>
lookfor <search> -all
