MATLAB: Variable in local function in livescript

Question

In livescript,

I define

a=1;

Then define a local function

function y = multi(x)
y = a*x;
end

This will give an error message. How can I define a as a global variable?

Answer 1

The variable a is defined in base workspace and hence, the error is because of the unavailability of variable a in function workspace. To share the data from base workspace with function workspace, you may make the variable a global.

global a
a = 1;

You also need to declare a as global in the function

function y = multi(x)
global a
y = a*x;
end

You may refer the following documentation for different practices of sharing data between workspaces
