create a script to read a .sgfx file and write to a .txt file in matlab

You can read the data from the binary .sgfx file using fread function in MATLAB and write it to a text (.txt) file using fprintf function. Here's a sample script:

main.m
% file paths
sgfxFilePath = 'example.sgfx';
txtFilePath = 'example.txt';

% open the binary file
fid = fopen(sgfxFilePath, 'rb');

% read data from the binary file
data = fread(fid, [nRows nCols], 'double'); % replace nRows and nCols with actual values

% close the binary file
fclose(fid);

% open the text file
fid = fopen(txtFilePath, 'w');

% write data to the text file
fprintf(fid, '%f ', data(:)); % colon operator to linearize the data

% close the text file
fclose(fid);
480 chars
22 lines

Note that you need to replace nRows and nCols with the actual number of rows and columns in the .sgfx file, respectively. Also, you may need to adjust the format of the data in the fprintf function, depending on the desired text format.
