Maple expressions can be evaluated in MATLAB using the
,
and
commands. More information about these commands can be found in the help system by typing the following commands into the worksheet:
,
and
The
command evaluates the expression in MATLAB. The
command assigns a value to a variable in MATLAB, while the
command returns the result stored in a MATLAB variable. The next two examples illustrate how to use these commands.
Example 1
The version of MATLAB with which the Maple-MATLAB connection is established can be determined using the
and
commands:
| (2) |
** Note: MATLAB returns the result of any expression in a variable called ans if no other variable has been specified by the user.
Example 2
The following example calculates the product of two Matrices,
, in MATLAB and returns the result in Maple. The Matrices are defined in both Maple and MATLAB.
| (3) |
| (4) |
The Matrices defined in
and
are copied to the MATLAB variables
and
using the
command.

:
The
command can be used to ensure that the variables defined in
and
were actually stored
in the variable
and
. As expected, the
command returns
if a variable is defined in MATLAB, and
otherwise.
=
=
The product of the two Matrices can now be calculated in MATLAB.
