assignin
Assign value to variable in specified workspace
Syntax
Description
assignin(
assigns the value ws
,var
,val
)val
to the variable var
in the workspace ws
. For example, assignin('base','x',42)
assigns the value 42 to the variable x
in the MATLAB® base workspace.
If val
requires evaluation, MATLAB evaluates it in the function that calls assignin
, not in the workspace specified by ws
. If val
is a function handle, it must be evaluable in the function that calls assignin
.
The assignin
function is useful for these tasks:
Exporting data from a function to the base workspace.
From within a function, changing the value of a variable that is defined in the workspace of the caller function. For example, you can change the value of a variable in the calling-function argument list.

Tips
The
assignin
function does not assign values to specific elements of an array. Thereforevar
cannot contain array indices. This code results in an error.X = 1:8; assignin('base','X(3:5)',-1);
To assign values to specific elements of an array, use the
evalin
function.evalin('base','X(3:5) = -1')
