Hello,
i want to create the following lines with my Matlab Code:
model.component('comp1').coordSystem.create('sys1', 'Cylindrical');
model.component('comp1').coordSystem.create('sys2', 'Cylindrical');
model.component('comp1').coordSystem.create('sys3', 'Cylindrical');
But its not 3 rows in every case so this number should be a variable.
I guess I need to work with a loop but I wont make it work.
Can someone help me?
THANK YOU!

I mixed my models up so there are no quotations marks, its fine, thank you!
I am not sure if I get it right with the fprintf(), so for example I want to print this 3 parts in the comsol_project_11b.m:
model.component('comp1').coordSystem.create('sys1', 'Cylindrical')
model.component('comp1').coordSystem.create('sys2', 'Cylindrical')
model.component('comp1').coordSystem.create('sys3', 'Cylindrical')
model.component('comp2').coordSystem.create('sys1', 'Cylindrical')
model.component('comp2').coordSystem.create('sys2', 'Cylindrical')
model.component('comp2').coordSystem.create('sys3', 'Cylindrical')
Code.placeholder.without.input.variables
model.component('test').coordSystem.create('systest1', 'Cylindrical')
model.component('test').coordSystem.create('systest2', 'Cylindrical')
model.component('test').coordSystem.create('systest3', 'Cylindrical')
model.component('test2').coordSystem.create('systest1', 'Cylindrical')
model.component('test2').coordSystem.create('systest2', 'Cylindrical')
model.component('test2').coordSystem.create('systest3', 'Cylindrical')
_______________________
First part is what I already got.
Second part is just simple lines(like text) without prefixes what I get from simply this:
output = "Code.placeholder.without.input.variables";
outfilename = 'comsol_project_11b.m';
[fid, msg] = fopen(outfilename, 'wt');
if fid < 0; error('Failed to open output file because "%s"', msg); end
fprintf(fid, '%s\n', output(:));
fclose(fid)
clear(outfilename); %clears any cached script
Third part is a varaiation of part one which I would get from:
component_prefix = "test";
component_number = 1:2; %row
sys_prefix = "systest";
sys_numbers = (1:3).'; %column
output = "model.component('" + component_prefix + component_number + "').coordSystem.create('" + sys_prefix + sys_numbers + "', 'Cylindrical')";
outfilename = 'comsol_project_11b.m';
[fid, msg] = fopen(outfilename, 'wt');
if fid < 0; error('Failed to open output file because "%s"', msg); end
fprintf(fid, '%s\n', output(:));
fclose(fid)
clear(outfilename); %clears any cached script
Not really find a working way to right this three part in one output file (the comsol_project_11b.m)
THANK YOU WALTER!!

the following line seems to help me:
output = output + newline
But the result duplicates the first output testlines for some reason:
MY CODE:
output = "test_line1";
output = output + newline + "test_line2";
output = output + newline + "test_line3;";
component_prefix = "comp";
component_number = 1:2; %row
sys_prefix = "sys";
sys_numbers = (1:3).'; %column
output = output + newline + "model.component('" + component_prefix + component_number + "').coordSystem.create('" + sys_prefix + sys_numbers + "', 'Cylindrical')";
outfilename = 'comsol_project_11b.m';
[fid, msg] = fopen(outfilename, 'wt');
if fid < 0; error('Failed to open output file because "%s"', msg); end
fprintf(fid, '%s\n', output(:));
fclose(fid)
clear(outfilename); %clears any cached script
PRINTS:
test_line1
test_line2
test_line3;
model.component('comp1').coordSystem.create('sys1', 'Cylindrical')
test_line1
test_line2
test_line3;
model.component('comp1').coordSystem.create('sys2', 'Cylindrical')
test_line1
test_line2
test_line3;
model.component('comp1').coordSystem.create('sys3', 'Cylindrical')
test_line1
test_line2
test_line3;
model.component('comp2').coordSystem.create('sys1', 'Cylindrical')
test_line1
test_line2
test_line3;
model.component('comp2').coordSystem.create('sys2', 'Cylindrical')
test_line1
test_line2
test_line3;
model.component('comp2').coordSystem.create('sys3', 'Cylindrical')

Ran in:
component_prefix = "comp";
component_number = 1:2; %row
sys_prefix = "sys";
sys_numbers = (1:3).'; %column
output = "model.component('" + component_prefix + component_number + "').coordSystem.create('" + sys_prefix + sys_numbers + "', 'Cylindrical')"
output = 3×2 string array
"model.component('comp1').coordSystem.create('sys1', 'Cylindrical')" "model.component('comp2').coordSystem.create('sys1', 'Cylindrical')" "model.component('comp1').coordSystem.create('sys2', 'Cylindrical')" "model.component('comp2').coordSystem.create('sys2', 'Cylindrical')" "model.component('comp1').coordSystem.create('sys3', 'Cylindrical')" "model.component('comp2').coordSystem.create('sys3', 'Cylindrical')"

Is it possible to right just the last 3 lines into an other file? Like an other m-file? So just the code I need without the "output = 3×2 string array"?
