[r,c] = find (bwlabel (BW)==2) You can display the output matrix as a pseudocolor indexed image. A confusion matrix, in predictive analytics, is a two-by-two table that tells us the rate of false positives, false negatives, true positives and true negatives for a test or predictor malignant) and the second class corresponds to a negative diagnostic (e Because this is a binary classification problem, the classes are "normal" and Work with your files from anywhere, share with others. The way I would suggest using it is to use the P (probability) values: [R,P] = corrcoef (X) [pr,pc] = find (P < 0.05) and search for the lowest ones, or those that exceeded your limits, for instance P < 0.05 or lower. In applications such as image processing , it can be useful to compare the input of a convolution directly to the output. In MATLAB, you can construct a sparse matrix using scalar expansion.
