Read text file and save result

I want to read X and Y axis from a text file, store them in a matrix, and then use "fprintf" to save the results.

I do not want to use "identifier" in the code.

This is the text:

2 # version

2 # sdim

10 # number of points

0 # lowest mesh point index

point coordinates

0 0 

0 0.10000000000000001

I appreciate any suggestion.

Thank you in advance.

I use the following code. I want to modify the code without using "identifier".

 function [PointMatrix] = m ( ~ )

 i = 1; 

 identifier = {' point coordinates'};

 addpath('C:\Users \Desktop');

 fid = fopen(strcat(point '. txt'));

 while ~feof(fid)

    readLine = cellstr(fgets(fid));

    if strcmp(readLine, identifier(1))

        while(~strcmp(readLine, cellstr('')))
            readLine = cellstr(fgets(fid));

            Point(i, :) = readLine;

            i = i+1;
        end

        Point(end, :) = [];

        for i = 1:size(meshPoint, 1)
            PointMatrix(i, :) = str2num(cell2mat(Point(i)));

        end

        clear 'Point';

        i = 1;

        end

 infmt = '%f%f';
 headers = 5;

 fid = fopen('YourFile.txt', 'rt');
 datacell = textscan(fid, infmt, 'HeaderLines', headers, 'CollectOutput', 1);
 fclose(fid);

 YourVariable = datacell{1};
 save('AppropriateFile.mat', 'YourVariable');

 outfmt = '%g %g\n';
 fprintf(outfmt, YourVariable .' );

Many thanks for the response.

Could you please also take a look on my code.

In the real text ( headers = 5;) is not correct.

[Walter Roberson]

I would need a real file. For example I cannot tell from what you posted whether the lines are double-spaced or if you put blanks between the lines for posting purposes.

[Maryam Hamrahi]

I attached the file.

I would like to read X and Y axis without using "identifier"

Thanks

[Walter Roberson]

Please indicate why you are trying to avoid using that particular string in the code. Your answer will affect the problem.

Will it be required to read in anything from the Types, such as the Elements, or the parameters (near line 7292)? Will it be necessary to allow for multiple Objects?

[Maryam Hamrahi]

I just want to read X and Y axis. save them in a matrix and using fprintf to create another text file.

I want to avoid using "identifier".

If you could help me with reading X and Y, then I could extend the code myself.

I want to have my code without this line:

 identifier = {'# Mesh point coordinates'};

[Walter Roberson]

Sorry, I cannot assist you until you answer the questions.

You should consider looking at http://www.mathworks.com/matlabcentral/fileexchange/14526-mph2stl

[Maryam Hamrahi]

Many thanks for the response.

I could not answer you because I am new in Matlab.

I saw this link before but I does not work for me.

However, Thanks a lot for your time and effort.

[Walter Roberson]

You can answer the question about why it is important to not use '# Mesh point coordinates' .

[Maryam Hamrahi]

Because I want to read different parts of the code like "# Geometric entity indices"

when I use the following

 identifier = {'# Mesh point coordinates','# Geometric entity indices'};

The code could not read "# Geometric entity indices".

So, I want to avoid using "identifier" and write the code in a different way.

Please see the attached file, this text file is much simpler.
