The columns of the table contain the classification results for each SVM classifier. Ideally, the table would be a diagonal matrix, where each diagonal element equals the number of images per digit (12 in this example). Based on this data set, digit 1, 2, 3, and 4 are easier to recogn...
I need to extract the different headings and the second and third column of data following these headings into different sections so as to evaluate them individually. Attached is a text file which is a simple version of my large data file. I want Matlab to store ...
Find the table rows with unique values in the first variable Age. If you only want one table variable to contain unique values, you can use the indices returned by unique to extract those rows from the table. Get [C,ia] = unique(A.Age); B = A(ia,:) B=3×3 table Age Height ...
Remember that the indices returned by the getSelectedRows and getSelectedColumns methods are 0-based, so when you use them to index into the MATLAB variable, "tableData", you will need to add 1 since MATLAB uses 1-based indexing. The resulting "selected...
4-16 Working with Matrices Deleting Rows and Columns You can delete rows and columns from a matrix using just a pair of square brackets. Start with X = A; Then, t ete the second column of X, use X(:,2) = [] This changes X to X = 16 2 13 5 11 8 9 7 12 4 14 1 If ...
The table contain these columns. ColumnDescription Age Age of the actor, returned as a positive integer. This value specifies the number of times the actor has been tracked. TrackID Track ID of the actor, returned as a numeric scalar, string scalar, or a character vector. ClassID Actor cla...
A table is a container that stores column-oriented data in variables. To access the data in a table, you can index into the table by specifying rows and variables, just as you can index into a matrix by specifying rows and columns. Table variables have names, just as the fields of a ...
