Hello everyone,
I need that MATLAB read a text file in the format below, and seperate each variables with corresponding numerics, and write it back with the format of the text file again. I want to add another variable with the same number of numerical values and write it back to its initial format to be read again by my program.
species 1
species 2
species 3
(0.1
0.2
0
)
(.02
.1
.5
)
(0.1
.2
.3
)
Then, I want to add Species 4 with some numerical values in the same format as othe variables.
Thank you so much.

S = fileread('YourFile.txt');
S = regexprep(S, '\)', '%g\n)');
newS = compose(S, ValuesForSpecies4);
fid = fopen('NewFile.txt', 'w');
fwrite(fid, newS);
fclose(fid);
My guess is that you will want to go slightly further and also insert the name of the 4th species. Possibly with something like
S = regexprep(S, '\(', 'name of species 4\n(', 'once');
