Input only numbers from .txt file and store numbers

Hi, i am trying to import ONLY numbers from a text file and then storing those numbers in seperate integers

for eg. if i write the following statement in my txt file

(X-coordinate of first element i node = 1 Y-coordinate of first element i node = 2 X-coordinate of first element j node = 3 Y-coordinate of second element j node = 4 ...)

and i want to store them in matlab like this

x1i=1

y1i=2

x1j=3

y1j=4

i have tried eveything from fscanf, fgetl, fopen. Any help or in this regard would be helpful.

It's generally bad form to spawn new variables like that, it will be much easier to manage a matrix—is that possible for you? It sounds like you will need to do some text parsing to get the integers or a simple regex to find an integer after "=", but I would provide the actual text file for us to help.

It would be better to write a more parseable text file, at least with a delimiter if not multiple records...

With just highlevel MATLAB functions

s='your string';
a=split([s '   '],'=');
a=a(2:end);
a=extractAfter(a,' ')'
v=str2double(extractBefore(a,' '))

returns the array 1:4

Of course, regular expressions would be the other way to go.

And, as Matt says above, don't even think about poofing variables into the namespace..."there be dragons!"
