Categorical Arrays. Arrays of qualitative data with values from a finite set of discrete, nonnumeric data. categorical is a data type to store data with values from a finite set of discrete categories. For example, the syntax C = categorical ( {'R','G','B','B','G','B'}) creates a categorical array with six elements that belong to the categories ...To create a multiline title, specify a cell array of character vectors or a string array. Each element in the array corresponds to a line of text. Example: h.Title = {'My','Title'}; If you specify the title as a categorical array, MATLAB ® uses the values in the array, not the categories. Accepted Answer. It seems like you want a list of the table's variable names, a list of the variable's types, and your 2xn cell array of names/types. Use t.Properties.VariableNames and varfun (@class,t,'OutputFormat','cell') to get the first two things. Then it seems like you'd want to use ismember )both outputs) on the variable …image (C) displays the data in array C as an image. Each element of C specifies the color for 1 pixel of the image. The resulting image is an m -by- n grid of pixels where m is the number of rows and n is the number of columns in C. The row and column indices of the elements determine the centers of the corresponding pixels.

T = table (T1,T2,T3) only works if all three tables have exactly the same number of columns AND exactly the same number of rows, and all columns are the same data type. If I had a 1000 tables, it would be nice if Matlab could index them: T (1) = T1; T (2) = T2; for i = 1:1000.Indexing into tables with parentheses, dot notation, and curly braces accesses table data in different ways. You can use indexing to create a table that is a subset of a larger table or to create an array from data in a table.
