I have text file as shown above..I only want to import numerical data from it.

Accepted answer

If test.txt is your txt file, the following code will create a cell C whose cell contains your data ( all of it ). You can iterate along the cell and retrieve the data you need/want.

fid=fopen('test.txt'); C=textscan(fid,'%s');

Answer by David Sanchez on 20 May 2013

fid=fopen('test.txt'); C=textscan(fid,'%s%s%s%s%s%s%s%s','delimiter','\n'); % read each line in string format fclose(fid)

data1 = char(C{1,2}); data1 = textscan(data1,'%s%s%f%f%f'); data1 = data1(3:5); for n = 1:3 num_data1(n) = data1{n}; end

num_data = zeros(3,3); for k =4:6 data= char(C{1,k}); data = textscan(data,'%s%f%f%f%f'); data = data(2:4); for n = 1:3 num_data(k-3,n) = data{n}; end end

Do you have the same number of "vertex" entries for each "facet" entry? So could each "facet" be converted to a 4 x 3 numeric array?

yes i have same number of vertex for each facet..yes it can be converted. how can i do that?
