getVar

Get variable from MuPAD notebook

MuPAD® notebooks will be removed in a future release. Use MATLAB® live scripts instead.

To convert a MuPAD notebook file to a MATLAB live script file, see convertMuPADNotebook. MATLAB live scripts support most MuPAD functionality, although there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

Description

example

MATLABvar = getVar(nb,'MuPADvar') assigns the variable MuPADvar in the MuPAD notebook nb to a symbolic variable MATLABvar in the MATLAB workspace.

Examples

collapse all

Copy a variable with a value assigned to it from a MuPAD notebook to the MATLAB workspace.

Create a new MuPAD notebook and specify a handle mpnb to that notebook:

mpnb = mupad;

In the MuPAD notebook, enter the following command. This command creates the variable f and assigns the value x^2 to this variable. At this point, the variable and its value exist only in MuPAD.

f := x^2

Return to the MATLAB Command Window and use the getVar function:

f = getVar(mpnb,'f')
f =
x^2

After you call getVar, the variable f appears in the MATLAB workspace. The value of the variable f in the MATLAB workspace is x^2.

Now, use getVar to copy variables a and b from the same notebook. Although you do not specify these variables explicitly, and they do not have any values assigned to them, they exist in MuPAD.

a = getVar(mpnb,'a')
b = getVar(mpnb,'b')
a =
a
 
b =
b

Input Arguments

collapse all

Pointer to a MuPAD notebook, specified as a MuPAD notebook handle. You create the notebook handle when opening a notebook with the mupad or openmn function.

Variable in a MuPAD notebook, specified as a variable. A variable exists in MuPAD even if it has no value assigned to it.

Output Arguments

Variable in the MATLAB workspace, returned as a symbolic variable.
