see Valid Combinations of Unlike Classes. Examples collapse all Two Matrices Concatenate two matrices vertically, then horizontally. For example, horizontally concatenate two matrices that both have two rows. If an increment value does not evenly partition the specified range, MATLAB automatically ends the sequence at the last value it can reach before exceeding the range. If I do C= [A,B] , it gives me the error "Duplicate table variable name". Similarly, all timetable inputs must have the same row times and all columns must have different names.

If the input sizes are not compatible, then MATLAB allows two types of concatenations Horizontal concatenation Vertical concatenation When you concatenate two matrices by separating those using commas, they are just appended horizontally. To concatenate several matrices, they must have compatible sizes. When concatenating horizontally, all table inputs must have unique variable names. Another possibility is to use cat where you specify the second dimension (column-wise) to concatenate the two matrices together. When you concatenate two matrices by separating those using commas, they are just appended horizontally. Without preallocation, MATLAB has to allocate memory every time the size increases, slowing down operations. List of inputs, specified as a comma-separated list of elements to concatenate in input along the second dimension. Ready to optimize your JavaScript with Rust? A = [1 2; 3 4] A = 22 1 2 3 4 B = [4 5 6; 7 8 9] B = 23 4 5 6 7 8 9 C = [A,B] C = 25 1 2 4 5 6 3 4 7 8 9 Now, horizontally append the second matrix to the first by using horzcat. horzcat is equivalent to using square brackets to horizontally If you have a specific set of data, you can arrange the elements in a matrix using square brackets. Create a table A with three rows and two variables. There are a few possibilities here. For example, [A,B] and [A B] concatenates arrays A and B horizontally, and [A; B] concatenates them vertically. In other words, when you concatenate matrices horizontally, they must have the same number of rows. All table inputs must have unique variable names. un] % Equivalent MATLAB code For horizontal concatenation, inputs must all have the same row dimension, M, but can have different column dimensions. The easiest, and most common one: The following is considered more robust by some, (because one might, on accident, do concat = [A; B], which would concatenate them vertically): Thanks for contributing an answer to Stack Overflow!
