Say, I have a matrix x = 0:0.5:20. Example: If a is a four by four matrix with values: 4 7 3. I would like to have something like that, [max,min,rightmaxcell,leftmax,cell]=Algorithm . Other MathWorks country It allows all arithmetic operations on a matrix, such as addition, multiplication, subtraction, etc. This has to go with the IBM Java Ideasubclass Browser (SCR-6). A (A>500) %This is the area I need help. It works fine in Matlab when I pre-populate the variables in the code: If you want to remove noise or to smooth your image, you can use the medfilt2 () function to create and apply the median filter to smooth the given image.

Baseline correction for data similar to Seismo-Signal. The zero-forcing class for this recieved filter is also implemented. Now to filter A it's just: The = [] sets the rows we want to filter to empty vectors which Matlab understands as removing those elements from the matrix.
