Code calculation output checker

So i have written some code which used a console command to do a calculation

The issue is that this console command doesnt work everytime. Running the same thing multiple times does produce different results(the console calculation, not the matlab code itself)

list=dir("RRfiles\");

for k = 1:length(list)
    command = sprintf('simpson RRfiles/RR%g.in', k);
    status = system(command);
end

Here is the trouble section of my code.

What simpson does is it takes in a set of values contained in the RR(X).in files and outputs a RR(X).fid file.

An example of a working .fid file is

SIMP
NP=128
SW=173333
TYPE=FID
DATA
0.499999941 0
0.466421028 0
0.469344476 0
.
.
.
0.270661094 0
END

And an example of a failed one is

SIMP
NP=128
SW=173333
TYPE=FID
DATA
0.499999941 0
1.#QNAN 1.#QNAN
1.#QNAN 1.#QNAN
.
.
.
.
END

What i need help with is writing a for loop that comes after this one that goes in the directory where i store the .fid files (something like c:\matlab\codelocation\fidfilelocation) and checks them all to see if they have worked on not, and if they havnt then it runs the console command again and then checks again afterwards, repeating this cycle till all of them have worked.

I know it is weird that the code doesnt work the same everytime. My current solution is to simply '!simpson RR(X).in' and check if it worked and repeat untill it does.

Mr rough idea so far is something like

zero = 0;
for loop 1:1000
    for i = 1:2
        text=fileread(['RR', num2str(i), '.fid']);
        strfind(text, 'QNAN');
        if ans>zero
            fprintf 'fail'
            command = sprintf('simpson RR%g.in', i);
            status = system(command);
        else
            fprintf 'pass'

        end
    end
end

list=length(H);

for k = 1:length(list)
    command = sprintf('simpson RRfiles/RR%g.in', k);
    status = system(command);
end
zero = 0;
for loop = 1:1000
    for i = 1:2
        QNAN_text=fileread(['RR', num2str(i), '.fid']);
        strfind(QNAN_text, 'QNAN');
        if ans>zero
            fprintf 'fail'
            command = sprintf('simpson RR%g.in', i);
            status = system(command);
        end
    end
end
fprintf 'all passed'

Its not perfect but it works

if contains(QNAN_text, 'QNAN')

Would be cleaner coding

[Charles Mitchell-Thurston]

So something like

for loop = 1:1000
    for i = 1:2
        QNAN_text=fileread(['RR', num2str(i), '.fid']);    
        if contains(QNAN_text, 'QNAN')
            fprintf 'fail'
            command = sprintf('simpson RR%g.in', i);
            status = system(command);
        end
    end
end
fprintf 'all passed'

I am concerned about the inconsistencies about using or not using the directory name.

Also fprintf does not emit newline unless you tell it to.

I don't think you should say all passed if you fail i==2 as well.

[Charles Mitchell-Thurston]

Currently the first part of my code is below. I got rid of the fprintf bit. And fixed the i = 1:2 to what it should be

%%%%take in data%%%%
H = readmatrix('numbers.xlsx');

%%%%create fid files%%%%

list=length(H);

for k = 1:list
    command = sprintf('simpson RRfiles/RR%g.in', k);
    status = system(command);
end
zero = 0;
for loop = 1:1000
    for i = 1:list
        QNAN_text=fileread(['RR', num2str(i), '.fid']);
        strfind(QNAN_text, 'QNAN');
        if ans>zero
            command = sprintf('simpson RRfiles/RR%g.in', i);
            status = system(command);
        end
    end
end
fprintf 'all passed'
mkdir Fidfiles

for t = 1:list;
    filename = ['RR', num2str(t), '.fid'];
    movefile ( filename, 'Fidfiles');
end
