Hi! Inside a function I do the fopen and textscan actions twice. I do not have any problems in the first time, but in the second, the values are not assigned to the matrix 'B'. The 'load(file.txt')' does not work either. Thank you in advance. I show you the code: fid=fopen(archivo_final,'r+'); A=textscan(f... 1 Jun 2010 15:17

Linear indexing
Hi there, I have an array of data within which I would like to be able to find the linear index of elements that satify a given condition. For example: data = [1,2,3,4,5,6,7,8,9,10]; find linear index of elements where data > 3 and data <6 . Pass linear index of these elements to a new arrray. I am su... 1 Jun 2010 15:17

Intergrating AVI file with EEG (CSV file)
Hi, In our experiment, we recorded video and EEG simultaneously as separate files, because we have to observe what is going on via video file and extract the EEG data for only specific parts that we need.

pcolor in Matlab
Hi All, I have been trying to use pcolor for plotting but have had no success for the past whole week. For example, if b1 and b2 are variables from the numerical solution of a pde then I set parameter1=linspace(.....); parameter2=linspace(.....); loop for parameter 1 and 2 D=b1-b2; find(D<0) pcolor(... 2 Jun 2010 12:01

A simple question
Hi I have a very simple/naive question. I am using a code(written below) to calculate the shortest paths between two network nodes. for i = 1: length(path) fprintf('Path # %d:\n',i); disp(path{i}) fprintf('dist of path %d is %d\n\n',i,dist(i)); end I get the paths along with their costs: Path # 1:... 1 Jun 2010 14:10
