MATLAB: Using single quotes with findstr

findstrsingle quotes

I have the following:

test = '''any word'''

which creates a char array containing the word with quotes

now i want to find the position of the quotes:

out = findstr(test,' '' ' )

but this doesn't work and returns an empty array. Can someone please explain how to do this and also why i cant use the escape sequence for single quotes i used to create the word in the first place.

Im using R2008b

Thanks

Matt

strfind(test,'''')

With ' '' ' you are looking for < blank>'<blank>

MATLAB: How to define string character

It creates a string (character array) containing just a single space character.

MATLAB: Is “findstr” not recommended compared to strfind.

R2012a says: "Note: findstr will be removed in a future release. Use strfind instead." This is a reason to replace findstr in code, which will be around for some years in the future.

And strfind is somewhat faster

    n2  = 1e6;
    a   = 'a':'p';
    buf = a( randi( [1,16], [1,n2] ) );
    str = reshape( buf, 1, [] );
    pattern = a( randi( [1,16], [1,4] ) );
    tic, ix1 = strfind( str, pattern ); toc
    tic, ix2 = findstr( str, pattern ); toc
    all( ix1==ix2 )

returns
