How can I specify that dlmwrite write to a textfile with the name of an input?

14 views (last 30 days)
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).

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.

What would be a typical response to
auxiliaryData = input('Input Auxiliary Channel: ')
? For example would it be a scalar that might be (for example) 2? And if so should that cause the file
/home/mydirectory/2.txt
to be the output file?

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.
