To directly find the elements in x that satisfy the condition x 5 use x x 5 avoid function calls like x find x 5 which unnecessarily use find on a logical matrix.

In a script file which contains commands and function definitions.
Now we will understand the above syntax with the help of various examples.
Functions are supported in scripts in r2016b or later.
The name of the file must match the name of the first function in the file.
Diff f diff f will differentiate f with the variable identified by symvar f 1 here is an example where we compute the differentiation of a function using diff f.

Script files cannot have the same name as a function in the file.
Let our input polynomial be x 2 x 6.
Functions must be at the end of the file.
Examples of derivative of function in matlab.
While pat matches a sequence of letters having any length strfind stops as soon as it finds a match and then proceeds to the next match.
This way you can create simple functions without having to create a file for them.
Matlab functions are written with various lines of code which relate one variable with another variable and each output is related exactly to one particular input that forms an important part of any programming language.
For example find and f are both matches for letterspattern since the number of letters for a match is not specified but strfind matches f first and returns its index.
In matlab environment they are stored in a certain file like script files etc.
