Locate and Extract a number out of a Text File

Hi guys,

I have a text file, in which there is a section looking like this:

 BLOCK SIZE USED ......................     7

 NUMBER OF DECOMPOSITIONS .............     4

 NUMBER OF ROOTS FOUND ................   211

 NUMBER OF SOLVES REQUIRED ............    77

I need to write a code which extracts the "211" value from the line "Number of Roots".

I have written the following script, which locates the line in the text file but I am unable to extract the number "211". Does anyone have an idea?

Here is what I wrote: >> CODE

fid = fopen('BIO-PDR_Stowed_Modal.f06','r') ;

Parser_REV_line = fgetl(fid);

while ischar(Parser_REV_line) % While loop to locate the target data in the f06 file

Parser_REV_line = fgetl(fid);

if contains(Parser_REV_line,'NUMBER OF DECOMPOSITIONS')

break

end

end

Parser_REV_line = fgetl(fid) ; % Returns the next line of the specified file, removing the newline characters.

while ischar(Parser_REV_line) % While the returned lined is a character array...

Parser_REV_line = fgetl(fid); % Get next line

if ~isempty(str2num(Parser_REV_line)) % IF the line returned, converted from string to numeric matrix is not empty...

%%%% This is where I can't extract the number %%%

end

if contains(Parser_REV_line,'NUMBER OF SOLVES REQUIRED') % When Parser_PF_line is equal to "NUMBER OF SOLVES REQUIRED" (i.e. end of data), program ends

break

end

end

fclose(fid) ;
