Hi, all.
I am trying to run the binaries in the matlab command window via system function.
The thing is, when I run the exact same code in the bash shell script, it's completely fine.
But it doesn't work in the matlab system function.
For example,
$ somefunc Input Output
works just fine in the shell,
but
>> system("somefunc Input Output")
is not working...
By typing
>> system("somefunc")
I realized that the shell opened through matlab recognizes the function but only when input is given, it complains saying,
"terminate called after throwing an instance of 'std::logic_error'
what(): basic_string:_S_construct not valid"
Any ideas about how to deal with this?
I'd really appreciate your help!!
btw, my matlab version is R2021b.

If you want to store the Output and use multiple arguments, please run like the following format.
>> [status, cmdout] = system("test.bat 4 5")
status =
0
cmdout =
'9
'
Or
>> ! test.bat 3 4
7

Thanks all for answering,
I found out that, running matlab in the bash shell inherits the enviroment running on the shell.
So running matlab through the bash shell script solved the problem!
