Executing matlab script from static directory with current path as input in linux (as alias)

Hello everybody.

I am currently trying to execute a matlab script from a static directory with inputs from dynamic ones as an alias. Basically I manually change the directory to where the files (inputs) are and then execute a matlab script with an alias. This alias should include the current path as well as the execution of the script from a static directory.

My solution so far is:

matlab -nojvm -nodisplay -nosplash -batch path=pwd;run('/pathToScript/script');

When using this solution the "error message" always is zsh:unknown file attribute. Im relatively new to linux.

When using the above solution in two separate steps:

matlab -nojvm -nodisplay -nosplash path=pwd;
%in matlab environment
run('/pathToScript/script');

it works just fine. So basically using the alias to do both executions is just for reducing time.

Thanks

matlab -nojvm -nodisplay -nosplash -batch "path=pwd;run('/pathToScript/script');"

However I would suggest it would be safer to

matlab -nojvm -nodisplay -nosplash -batch "addpath(pwd);run('/pathToScript/script');"

Thank you very much. This solves the problem of the execution of both commands. Do you know by any chance how to implement this in an alias? Using:

alias knock = 'matlab -nojvm -nodisplay -nosplash -batch "addpath(pwd);run('/pathToScript/script');"'

results in "Error: Invalid use of operator" for the "/" in /pathToScript. Somehow the " ' " is ended after run(' .

Thanks

alias knock="matlab -nojvm -nodisplay -nosplash -batch \"addpath(pwd);run(\\\"/pathToScript/script\\\");\""

It was tricky to get everything escaped just the right way.

At one level you are executing a shell command to create an alias. But the alias that is created has to be something that can be executed again, so you end up having to double-escape when building the alias.
