Loop to logical indexing
Hey, I am trying to get rid of this loop and possibly use of logical indexing to make this more efficient. for i=1:length(Returns) if(Returns(i,:) > 0) BothPos(i,1) = 1; else BothPos(i,1) = 0; end end BothPos = sum(BothPos); I have a matrix of returns "Returns". And I want t... 14 May 2010 11:41

Align T zero
I have two sets of acceleration data, a1 with t1, a2 with t2 from the same object but different accelerometers. Length of data is different so that accelerometers were triggered on and off at different time before and after the event in question. What is the best method of aligning the data automatically to a commo... 14 May 2010 10:35

finding centroid of an 3d object
Hi I am trying to find the centroid of an arbitrary 3d shape object on MATLAB. THe 3D object is generated by slices of 2D images. By as we move across each 2D slice, the shape of the object change.

I'm using the trim command in the format: [x, u, y, dx] = trim ('model', x0, u0, y0, ix, iu, iy); It seems to be returning reasonable state values, x, and output values, y. But the inputs, u, don't work. I have specified in iu the indexes of the elements of u0 to remain unchanged, however the trim command doesn't... 13 May 2010 19:22

stretching text
Hello, anyone know how to vertically stretch a letter in Matlab so that its width is the same. I want to create a visualization similar to the seqLogo function in the bioinformatics toolbox, in which the height of the letter represents some quantity. Simply increasing the font size won't work as this increases the widt... 26 May 2010 14:41
