Loading File with Interspersed text and numbers

Hi, I have a .log file that's in the following format:

3 lines of text

5 columns of numeric data (25-30 rows)

3 lines of text

5 columns of numeric data (25- 30 rows)

...and it keeps going for 14 more times.

I want to load this file into a cell array, having each line of the file as one cell. How do I do this?

Any help will be greatly appreciated. Thanks!

You want to try fscanf. The documentation: http://www.mathworks.com/help/techdoc/ref/fscanf.html

One of the examples:- % Create a file with temperatures tempstr = '78°F 72°F 64°F 66°F 49°F';

fid = fopen('temperature.dat', 'w+');
fprintf(fid, '%s', tempstr);

% Return to the beginning of the file
frewind(fid);

% Read the numbers in the file, skipping the units
% num_temps is a numeric column vector

degrees = char(176);
num_temps = fscanf(fid, ['%d' degrees 'F']);

fclose(fid);

Try something like that. If there are numbers in between the lines, Try to set a condition which checks before the number and after the number for the type. If it is character before and after then ignore that number. There you go.
