python call matlab file
In the current directory, the establishment of MATLAB script file triarea.m, reads as follows
b = 5;
h = 3;
a = 0.5*(b.* h)
Create a new directory with test.pyFor calling triarea.m document reads as follows
import matlab.engine
eng = matlab.engine.start_matlab()
eng.triarea(nargout=0)
Run python file
D:\ProgramData\Anaconda3\python.exe D:/code/python/test.py
a =
7.5000
Process finished with exit code 0
python function call matlab
MATLAB to create a function file, as follows:
function a = triarea(b,h)
a = 0.5*(b.* h);
test.py file amended as follows:
import matlab.engine
eng = matlab.engine.start_matlab()
ret = eng.triarea(1.0,5.0)
print(ret) # 2.5
D:\ProgramData\Anaconda3\python.exe D:/code/python/test.py
2.5
