For example, I want to write a text file to a directory using dlmwrite, and I want to name the text file as the inputted name. I have:

    dlmwrite('/home/mydirectory/auxiliaryData',output, 'delimiter','\t','precision',10 );

and a couple of lines of code ago, I had:

auxiliaryData = input('Input Auxiliary Channel: ');

I don't want the name of the text file to be the name of the variable (auxiliaryData).

在 MATLAB Online 中打开

projectdir = '/home/mydirectory';
dlmwrite( fullfile(projectdir, auxiliaryData),output, 'delimiter','\t','precision',10 );

You might prefer using

auxiliaryData = input('Input Auxiliary Channel: ', 's');

... I'm not really sure what data type you intend, or what file extension you intend.

The input will be a text file filled with matrices of doubles that is within a lot of nested directories.

So one typical input would be:

/home/pulsar/public_html/fscan/L1_DUAL_ARM/L1_DUAL_ARM_DCREADOUT_HANN/L1_DUAL_ARM_DCREADOUT_HANN/fscans_2015_10_01_06_00_02_CDT_Thu/L1_CAL-DELTAL_EXTERNAL_DQ/spec_0.00_100.00_L1_1127646019_1127732419.txt

Also, I'm getting another error message when I run this matlab program. It says "Could not open file"

I believe this is because the directory and text file which I'm accessing the data from are read-only. So I think you're code is outputting back into that directory.

I'm not too sure what the problem is.
