Array Manipulation, Signal Processing
Hey Everybody, I'm very new to this so the answer may be very simple, but I am dealing with a very large array (several million data points) and I want to be able to create a new array where certain data points from the original would be removed (set to zero).

fread and float
Dear all, I have a binary file where each record is 53 byte long. Starting from byte 26 to byte 29 I have a Microsoft Binary Float used to store a date which should be in the format 'yyyymmdd'. So, if I read the file in with fread(fid,4,'uint32') I get 4 values which I assume are the first chunk of 8 bits, the sec... 13 Jul 2010 14:13

Sorry for this elementary question but I couldn't seem to find the answer anywhere.... I have a matrix for which I have changed the nth column by typing B(:;n) = [x; x; x] but I wanted to store it as another matrix G. So something like G = B(:;n) = [x; x; x] except the above doesn't work. ... 12 Jul 2010 12:55

Average Every N rows in a Matrix
I currently have a data matrix that is 27359x26.

I am looking to get the average of every 10 rows but cannot seem to fig... 12 Jul 2010 18:30
