If statement help
I need help writing a single instruction that will take a vector y and change it such that any element of y that is less than pi is set to pi. I had this: y = [1 2 3 4 5] for k = 1:length(y) if y(k) < pi y = pi end end and I get ??? Attempted to access y(2); index out of bounds because numel(y)=1. ... 20 Apr 2010 19:40

TreeBagger missing values
I was wondering if anyone knew how the TreeBagger handles missing values. There seem to be two methods described in literature and by Breiman. One of these (apparently, the better one) uses a recursive/iterative method for computing the missing value. Does anyone know (for certain) which method is implemented? There... 20 Apr 2010 18:28

Trouble with textscan

Here is the example: UTC Launch Time (y,m,d,h,m,s): 2008, 10, 28, 03:27:29 I tried several things but the problem is that MATLAB gets confused by the "," delimiters. I tried for example: tmp=textscan(fid,'%s %s %s %s %f %f %f... 20 Apr 2010 20:47

How to get elements in a specific order from matrix
Hi all lets say we have a=[1 2 3 4 5 10 15 20 21 22 23 24 30 37 40] This matrix has two kinds of elements; the elements which follow specific order such [ 1 2 3 4 5] and [20 21 22 23 24 ] and the elements that not follow any order such[10 15 20 ]... I need to count how many times I have elements that follow i2=i1+... 20 Apr 2010 15:59

Clusters by k means based on sensor measurements
I have a N*3 matrix M(a,b,c) of sensor measurements. N is the number of sensors, "a" is the measurement of the sensor, "b" and "c" are the location of the sensor, say, the coordinate in a plane. I need to clustering the sensors by their measuements. I know I can use kmeans algorithm. But in the matlab help, the input m... 20 Apr 2010 15:58
