How to extract a column from cell arrays matrix?. Learn more about read from column in cell arrays matrix
I'm wondering if I can use directly the column (extracted from a matrix) inside the loop, for example or should I name if first because T1(:,8)(i) does not work A = zeros(length(T1(:,7)),length(T2(:,7))); fori=1:length(T1(:,7))...
select the “Matrix Columns” checkbox and press the “Edit” button in the “Objects” group. The following window will appear. In this window, select the columns with index of 1 to 700 and press the OK button.To extract the data to Y, repeat the process selecting only the column 701...
trainingImages is a 200-by-10 cell array of training image file names; each column contains both the positive and negative training images for a digit. trainingLabels is a 200-by-10 matrix containing a label for each image in the trainingImage cell array. The labels are logical values indic...
Example 3: Using TEXTREAD to read in text and numeric data from a file with headers % This command skips the 2 header lines at the top of the file % and reads in each column to the 4 specified outputs [c1 c2 c3 c4] = textread('sample_file2.txt','%s %s %s %s','headerlines',2...
I have a 103x6 matrix. First column consists of strings (either Picture or Response). Unfortunately some of my subjects committed errors during the task and forgot to push a button (therefore, no Response after Picture). So I would need only those rows when a Picture ...
