Question

I got the answer from the following question. It asks me to create a bash file. The question is in the title

How to call MATLAB functions from the Linux command line?

Thus I tried the following code, as given in the answer.

    b_exec=matlab
    X="localize(r,q)"
    echo ${X} > matlab_command_rq.m
    cat matlab_command_rq.m 
    ${matlab_exec} -nojvm -nodisplay -nosplash < matlab_command_rq.m
    rm matlab_command_rq.m

The original code in the answer was

    matlab_exec=matlab
    X="${1}(${2})"
    echo ${X} > matlab_command_${2}.m
    cat matlab_command_${2}.m
    ${matlab_exec} -nojvm -nodisplay -nosplash < matlab_command_${2}.m
    rm matlab_command_${2}.m

In the explanation, they mentioned that $1 was function and $2 was inputs. correspondingly, I replaced it with my function ‘localize’ and inputs (r,q)

But I got the following error

    localize(r,q)
    ./matlab_batcher.sh: 5: ./matlab_batcher.sh: -nojvm: not found

The echo seems to be working. But I really do not know what is happening after that. Could you please help me and tell me the right way to call the matlab function with its arguments???

I called it using the following statement

   sh ./matlab_batcher.sh localize r q

Answer 1

You need to change your b_exec back to matlab_exec, or you need to change

${matlab_exec} -nojvm ...

to

${b_exec} -nojvm ...

Either way, you need to make it consistent.
