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:

** 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.

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.

The Matlab package also provides the users with the ability to perform several Matrix manipulation operations in MATLAB without the explicit use of the ,   and   commands. These commands are listed in the table below:

For instance, using the  command, the determinant of a Matrix can be evaluated directly in MATLAB, and the result will be automatically returned in Maple. It is important to note, that all of the commands listed in the table above can be applied to Matrices defined in both Maple and MATLAB.

It is important to remember, that the Matrix defined in the variable   is stored in MATLAB and not in Maple.
