set command in matlab

In Matlab, you can set a command by creating a variable and assigning it a value or expression. The variable can be any valid name, alphanumeric or contains underscores _, but it cannot start with a number or contain spaces. Here's an example:

main.m
my_variable = 5 + 7;
21 chars
2 lines

In this example, the command 5+7 is evaluated and the result (12) is assigned to the variable my_variable.

You can also define a function in Matlab using the function keyword. Here's an example:

main.m
function output = my_function(input)
    output = input * 2;
end
65 chars
4 lines

In this example, we define a function called my_function that takes an input argument and returns the result of multiplying it by 2. The function is saved in a file with the same name as the function (my_function.m) in the Matlab's working directory.

These are just two basic examples, but Matlab provides many more ways to set commands and create complex programs.
