matlab global

In MATLAB, the 'global' keyword is used to declare variables as global variables. Global variables are variables that can be accessed and modified from any function or script in the MATLAB workspace.

To declare a variable as a global variable, the 'global' keyword is used followed by the variable name. For example, to declare a variable 'x' as a global variable, the following code can be used:

global x

Once a variable is declared as a global variable, it can be accessed and modified from any function or script in the MATLAB workspace using the same variable name. For example, if a function named 'myFunc' needs to access and modify the global variable 'x', the following code can be used:

function myFunc()
global x
x = x + 1;
end

In this example, the 'myFunc' function accesses the global variable 'x' and increments its value by 1. The modified value of 'x' can then be accessed from any other function or script in the MATLAB workspace.
