Getting a specific value from a matrix


    Apr 26 2013 | 4:26 pm
    Hi,
    I am trying to get all the 0 values from one matrix and write them to another matrix. I am sure there is an easy way to do this but I could not figure it out.
    Thanks.

      you could do something like [jt.expr @expr if in[0] == 0 then 0 else 1]
      but you'll have to htink what you want to fill teh rest of your matrix with (i assumed 1 here), cause you can't create an incomplete matrix, you must fill all its cells at once.

      I tried it but couldn't make it work. Probably I am doing something wrong.

      Oh, nevermind. [jit.gen bool] seems to work.
