how to concat two strings with data from external file inbetween?

Hi,

I have two strings:

string1='Simpson'

string2='Wilder'

I also have an external text file, called numbers.txt whose content is:

1

11

23

46

76

I would like to read numbers.txt and write the following to an external file, called concat.txt

Simpson,1,Wilder,

Simpson,11,Wilder,

Simpson,23,Wilder,

Simpson,46,Wilder,

Simpson,76,Wilder,

How can I do this in MATLAB?

I thank you in advance,

Best regards,

To read your input data, you could use the function readmatrix. Then, the function strcat is what you want to use to perform your string operations. The last step would be using writematrix to write down your concat txt file.

One approach, I'm sure there are others:

first = "Simpson";
last  = "Wilder";
nums = string(readmatrix('input.txt'));
out = first + "," + nums + "," + last;
writematrix(out,'output.txt','QuoteStrings',false);
