I've inherited an m-file that calls the function:
function conditions(varargin)
This requires me to type a series of names when running the m-file. E.g.,:
conditions('c01','c02','c03')
I also have a text file (conditions.txt) that contains all conditions names, one conditions per line. e.g.,:
'c01'
'c02'
'c03'
etc...
Is there a way to automate conditions.m through the Bash shell by running through each line of the text file, one line at a time?
Since you're happy to take other suggestions as well, I'm going to suggest you do this through a simple MATLAB script. MATLAB takes a while to start up, so it is quite inefficient to start MATLAB anew for each "condition".
I'm going to assume that your text file example is a simplification, maybe you have multiple parameters per line, and need to pass each of them as an argument to the conditions function. For example the file conditions.txt could contain:
'c01',5,false
'c02',100,true,0,'foo'
...
and you'd want to generate the calls
conditions('c01',5,false)
conditions('c02',100,true,0,'foo')
...
The following code accomplishes this:
f = fopen('conditions.txt','rt');
while true
data = fgetl(f);
if isequal(data,-1), break, end
eval('conditions(',data,')')
end
fclose(f);
exit
You could save that as an M-file script (e.g. runconditions.m), and execute it from bash as follows:
matlab -nosplash -nodesktop -r runconditions
eval is evil, in general, but in this case it's the same as what you'd be doing from the Bash script in Christian's answer. The only difference with that answer is that you avoid starting up MATLAB repeatedly.
At least on windows you can call matlab functions from batch like this: matlab -wait -r 'conditions(%var%)'
So your bash looping should be solvable with a code snipped like this:
while read p; do
matlab -wait -r 'conditions($p)'
done <yourfile.txt
Or any other looping style of your choice: Looping through the content of a file in Bash
echo $p into the while loop it shows each line?
conditions(), easier, no?
