R-0

{

position (0.2 1.48 0.01);

pRef 2.0e-5;

fftFreq 1024;

}

I want to write a matlab script to produce a text file having a repated lines like the above line while changing the values inside

R-i

{

position (x(i) y(i) 0.01);

pRef 2.0e-5;

fftFreq 1024;

}

where, i, x(i) and y(i) are imported from x file

clc;
clear;
Excel= xlsread('receiverlocations.xlsx','points') ;
x= Excel(:,1)';%x
y= Excel(:,2)';%y
fid = fopen('ny.txt','wt');
for i=1:length(x)
    i=i;
    fprintf(fid, '{\n');
    fprintf(fid, 'R-');
    fprintf(fid,'i');
    fprintf(fid, '\n');
    fprintf(fid,'position','%6s %12s','x(i)','%6s %12s\n','y(i)');
    fprintf(fid, '\n');
    fprintf(fid, '}\n');
    fprintf(fid, '\n');
end
fclose(fid)

I have tried the previous lines but variable like i is printed as i not the corresponding value

can anyone help?

You forgot to put in the arguments as data:

clc;
clear;
Excel= xlsread('receiverlocations.xlsx','points') ;
x= Excel(:,1)';%x
y= Excel(:,2)';%y
fid = fopen('ny.txt','wt');
for i=1:length(x)
    pRef=___
    fftFreq=____
    fprintf(fid, [...%split on multiple lines for readability, use 1 statement for speed
        'R-%d\n',...
        '{\n',...
        '    position   %.2f   %.2f\n',...
        '    pRef       %e\n',...
        '    fftFreq    %d\n',...
        '}\n',...
        '\n'],...
        i,x(i),y(i),pRef,fftFreq);
end
fclose(fid)
