How can I remove apostrophe from a number?

I want to rad data from a text file. But I got a problem : MATLAB can't read a number with an apostrophe (158'289.641000 for example).

I want to convert it into that number : 158289.641000

This code works until the first number with apostrophe :

fid= fopen('test.txt', 'r');

rawdata= textscan(fid, '%s %s %s', 'headerlines', 44);

fclose(fid)

tmel = rawdata{1,1};

Imel = rawdata{1,3};

[Arthur Savioz]

For example 12'500

apostrophe is the ' caractere

This works

fullFileName = fullfile(pwd, 'MATBIP_04_Channel_1.txt');
% Open the file for reading in text mode.
fileID = fopen(fullFileName, 'rt');
% Read the first line of the file, but don't use this header line.
textLine = fgetl(fileID);
% Read the second line of the file.
textLine = fgetl(fileID);
lineCount = 0;
while ischar(textLine)
	lineCount = lineCount + 1;
	% Print out what line we're operating on.
	fprintf('%s\n', textLine);
	% Get rid of quotes
	textLine(textLine == '''') = [];
        % Parse string into numbers.
	numbers(lineCount, 1:3) = sscanf(textLine, '%f	%f	%f');

	% Read the next line.
	textLine = fgetl(fileID);
end
% All done reading all lines, so close the file.
fclose(fileID);
