After importing a csv file I see that a variable 'textdata' has been created. It is identified by curly brackets. In row 1, column 1 is the information I want. Here's an example:

This is the name of the CSV file:

C:\Program Files\BOSE\Etienne\Data files\WW series_block tests\WW11cRH_29May2012.TXT

I want to create a variable as follows:

SampleDescrip='WW11cRH-29May2012'

(Ideally I want to replace the underscore in the original name with a dash).

Thank you.

在 MATLAB Online 中打开

regexprep('WW11cRH_29May2012.TXT','_','-')

EDIT

name          = 'C:\Program Files\BOSE\Etienne\Data files\WW series_block tests\WW11cRH_29May2012.TXT';
[path,n]      = fileparts(name);
SampleDescrip = regexprep(n,'_','-');
