Yes, in MATLAB, you can create a .bin file in the workspace using the `fwrite` function. Here's an example of how you can accomplish this:
% Generate some data to write to the .bin file
data = rand(1, 1000);
% Create a file in the workspace directory
filename = 'data.bin';
fileID = fopen(filename, 'w');
% Write the data to the file
fwrite(fileID, data, 'double');
% Close the file
fclose(fileID);
In this example, `data` is an array of random numbers generated using the `rand` function. The `fwrite` function is then used to write the data to the file specified by `filename`. The `'double'` argument specifies the data type to be written.
You can modify this code to suit your specific needs. Once you have created the .bin file in the workspace, you can pass it to your MEX C function for zlib decompression. Remember to adjust the file path accordingly when calling your MEX function.
