assignin - Assign value to variable in specified workspace
Syntax
assignin(ws, 'var', val)
Description
assignin(ws, 'var', val) assigns the value val to the
variable var in the workspace ws. var is created if it doesn't
exist. ws can have a value of 'base' or 'caller' to denote the MATLAB base
workspace or the workspace of the caller function.
The assignin function is particularly useful
for these tasks:
Exporting data from a function to the MATLAB workspace
Within a function, changing the value of a variable
that is defined in the workspace of the caller function (such as a
variable in the function argument list)
Remarks
The MATLAB base workspace is the workspace that is seen
from the MATLAB command line (when not in the debugger). The
caller workspace is the workspace of the function that called the
M-file. Note that the base and caller workspaces are equivalent in
the context of an M-file that is invoked from the MATLAB command
line.
Examples
This example creates a dialog box for the image display function,
prompting a user for an image name and a colormap name. The assignin function is used to export the user-entered values
to the MATLAB workspace variables imfile and cmap.
prompt = {'Enter image name:','Enter colormap name:'};
title = 'Image display - assignin example';
lines = 1;
def = {'my_image','hsv'};
answer = inputdlg(prompt,title,lines,def);
assignin('base','imfile',answer{1});
assignin('base','cmap',answer{2});
