MATLAB: Regexp: extra cell layer in the output

Question

Greetings!

I try to decompose a complex header line in tokens:

>> HeaderLine = 'TEKTRONIX TDS 1012B Project Number:0 Sample Name: Depth: 0.000000';
>> regexp(HeaderLine,'^(.*) Project Number:(.*) Sample Name:(.*) Depth: (.*)$', 'tokens')
ans = 
      {1x4 cell}

However ans itself is a 1×1 cell, but not 1×4 cell as stated above.

Could you please suggest me a way to force regexp to output a pure 1×4 cell array of tokens?

Thank you in advance!

Answer 1

c = regexp(HeaderLine,'^(.*) Project Number:(.*) Sample Name:(.*) Depth: (.*)$', 'tokens');
out = c{:};
