Hi, I am stuck up with a simple query wherein I want to check if particular string exits in a given string. i.e. If I am using input image from following file path C:\New Folder\Level1\Image1.tiff Now I want to check if a string "Level1" exists in a given file path name. I want to know only its existence & not its length, position or occurrence. Simply in the form of true or false (o or 1). Can someone please help me with this. Thanks in advance for your help!

Look at these examples, and pick whichever one of the methods suits you best:

s = 'C:\New Folder\Level1\Image1.tiff'
template = 'Level1' % Cases match
foundIt = any(ismember(s, template))
index = strfind(s, template)
foundIt = ~isempty(index)
template = 'level1' % Case mismatch.
index = strfind(s, template)
foundIt = ~isempty(index)
template = 'level1' % Case mismatch.
index = strfind(upper(s), upper(template))
foundIt = ~isempty(index)
