Invoke a PackagedMATLABFunction

Invoke a compiled MATLAB®function using the Python®object returned from theinitialize()function.

result1,...resultN =my_client.function_name(in_args, nargout=娜戈,stdout=out_stream, stderr=err_stream)

  • my_client— Name of object returned frominitialize()

  • function_name— Name of the function to invoke

  • in_args— Comma-separated list of input arguments

  • nargs— Number of expected results. The default value is1.

  • out_stream— PythonStringIOobject receiving the console output. The default is to direct output to the console.

  • err_stream— PythonStringIOobject receiving the error output. The default is to direct output to the console.

Each variable on the left side of the function call is populated with a single return value.

Note

If you provide less thannargsvariables on the left side of the function call, the last listed variable contains a list of the remaining results. For example

result1,编写此表达式result2 = myMagic.triple (5 nargout=3)

leavesresult1containing a single value andresult2containing a list with two values.

InvokeMATLABFunction with Single Output

To invoke the MATLAB functionresult = mutate(m1, m2, m3)from the packagemutations, you use this code:

import mutations import matlab myMutator = mutations.initialize() m1 = matlab.double([1,2,3]) m2 = matlab.double([10,20,30]) m3 = matlab.double([100,200,300]) result = myMutator.mutate(m1,m2,m3)

InvokeMATLABFunction with Zero Outputs

To invoke the MATLAB functionmutate(m1,m2,m3)from the packagemutations, you use this code:

import mutations import matlab myMutator = mutations.initialize() m1 = matlab.double([1,2,3]) m2 = matlab.double([10,20,30]) m3 = matlab.double([100,200,300]) myMutator.mutate(m1,m2,m3,nargout=0)

Receive Multiple Results as Individual Variables

To invoke the MATLAB functionc1,c2 = copy(o1,o2)from the packagecopier, use this code:

>>> import copier >>> import matlab >>> myCopier = copier.initialize() >>> c1,c2 = myCopier.copy("blue",10,nargout=2) >>> print(c1) "blue" >>> print(c2) 10

Receive Multiple Results as Single Object

To invoke the MATLAB functioncopies = copy(o1,o2)from the packagecopier, use this code:

>>> import copier >>> import matlab >>> myCopier = copier.initialize() >>> copies = myCopier.copy("blue",10,nargout=2) >>> print(copies) ["blue",10]

Invoke aMATLABFunction in the Background

To invoke a MATLAB functionsumwrapfrom the packagesumwrapasynchronously, use this code:

>>> import sumwrap >>> import matlab >>> sw = sumwrap.initialize() >>> a = matlab.double([[1, 2],[3, 4]]) >>> future = sw.sumwrap(a, 1, background=True) >>> future.result() matlab.double([[4.0,6.0]])
