filecontent = fileread('NameOfTheFile.txt');
newcontent = regexprep(filecontent, '^[#:].$', '', 'lineanchors', 'dotexceptnewline');
You can use textscan() on the string newcontent:
numcols = 18
fmt = repmat('%g', 1, numcols);
datacell = textscan(newcontent, fmt, 'CollectOutput', 1);
data = datacell{1};

filecontent = fileread('NameOfTheFile.txt');
newcontent = regexprep(filecontent, '^[#:].*$', '', 'lineanchors', 'dotexceptnewline');
numcols = 18;
fmt = repmat('%f', 1, numcols);
datacell = textscan(newcontent, fmt, 'CollectOutput', 1);
data = datacell{1};
