I have matlab file matlab_param.m
function matlab_param(param1, param2)
disp(sprintf('param1 : %s', param1));
disp(sprintf('param2 : %s', param2));
And I want to have bash script bash_param.sh that look like
#!/bin/bash
echo $1
echo $2
./matlab_param.m $1 $2
I want to run this bashscirpt
./bash_param.sh hello world
and it will print
hello
world
param1 : hello
param2 : world
I googled for hours and couldn't find any exact solution for this. The closest one the I got so far is
matlab -nodesktop -nosplash -nodisplay -r "try, run ('./test_param.m'); end; quit"
which I need to hardcode all parameters.

To pass any number of arguments to the bash function simply put them right after the function's name, separated by a space. It is a good practice to double-quote the arguments to avoid the misparsing of an argument with spaces in it. The passed parameters are $1 , $2 , $3 …
To invoke a function, simply use the function name as a command. To pass parameters to the function, add space-separated arguments like other commands. The passed parameters can be accessed inside the function using the standard positional variables i.e. $0, $1, $2, $3, etc.
NUM} ) in the 2^32 range, so there is a hard limit somewhere (might vary on your machine), but Bash is so slow once you get above 2^20 arguments, that you will hit a performance limit well before you hit a hard limit.
Did you try:
#!/bin/bash
echo $1
echo $2
matlab -nodesktop -nosplash -nodisplay -r "try, test_param('$1','$2'); end; quit"
If you want to be able to pass arguments to matlab function I'd recommend to create a simple shell script:
matlab -nodisplay -r "try, test_param('$1','$2'); end; exit"
Then you can run in unix:
$ sh test_param.sh hello world
Not sure although how to avoid the MATLAB header output and if it will be passed to pipe.
