create csv file with user input and current date as name

Hello everyone

I want to create a csv file in desired location with name that include user input and current date.

I manage to create a csv file with the user input and the current date but I'm unable to save it in desired location

SN = input('Please enter the Serial Number ', 's');

fileName = sprintf('freq_res_data_%s_%s.csv',SN, datestr(now,'dd_mm_yy_HHMMSS'));

csvwrite(fileName,out);

I tried to run add the full direction (d:\tom\) but it doesnt work

I tried only on d:\ and it still deson't work

SN = input('Please enter the Serial Number ', 's');

fileName = sprintf('d:\tom\freq_res_data_%s_%s.csv',SN, datestr(now,'dd_mm_yy_HHMMSS'));

csvwrite(fileName,out);

tom folder is exist

how can I save in any other directory then the current folder?

Use sprintf to generate a local string variable. Use a \\ sequence to include a single \ in the string. Then pass the string as a filename to csvwrite.

» SN = '2'

SN =

'2'

» fileName = sprintf('d:\\tom\\freq_res_data_%s_%s.csv',SN, datestr(now,'dd_mm_yy_HHMMSS'))

fileName =

'd:\tom\freq_res_data_2_11_05_22_075347.csv'

Please post the code and any errors you are getting from MATLAB. Remove semicolons after statements so you can see return results.

>> test

Please enter the Serial Number 777

SN = 777

fileName = c:\freq_res_data_777_11_05_22_171425.csv

error: dlmwrite: Invalid argument

error: called from

dlmwrite at line 177 column 5

csvwrite at line 44 column 3

test at line 22 column 1

>> test

Please enter the Serial Number 777

SN = 777

fileName = d:\freq_res_data_777_11_05_22_171444.csv

can it be a permission issue?
