- You can use ismember + indexing to do your task: [idx1,idx2] = ismember(A(:,1:end-1), B(:,1:end-1), 'rows'); idx3 = ~ismember(B(:,1:end-1), A(:,1:end-1), 'rows'); C(idx1,:) = [A(idx1,:) B(idx2(idx1),end)]; C(~idx1,:) = [A(~idx1,:) zeros(sum(~idx1),1)]; C=[C;B(idx3,1:end-1) zeros(sum(idx3),1) B(idx3,end)];

Constructing a Matrix of Data. If you have a specific set of data, you can arrange the elements in a matrix using square brackets. A single row of data has spaces or commas in between the elements, and a semicolon separates the rows. For example, create a single row of four numeric elements.
https://www.mathworks.com/matlabcentral/answers/383970-how-can-i-combine-two-matrices. Commented: Matt J on 21 Feb 2018. Accepted Answer: Birdman. A = [1 2 3; 4 5 6; 7 8 9] B = [10 11 12; 13 14 15] C = [1 2 3; 4 5 6; 7 8 9; 10 11 12; 13 14 15]
Jan 3, 2018 · How can I combine 2 matrices A, B into one so that the new matrix C = row 1 of A, followed by row 1 of B, then row 2 of A, row 2 of B, row 3 of A, row 3 of B, etc? Preferably without a for loop? ex: A = [1 2 3; 4 5 6], B = [5 5 5; 8 8 8].
You can concatenate two matrices to create a larger matrix. The pair of square brackets ' []' is the concatenation operator. MATLAB allows two types of concatenations −. Horizontal concatenation. Vertical concatenation.
You can use the square bracket operator [] to concatenate or append arrays. For example, [A,B] and [A B] concatenates arrays A and B horizontally, and [A; B] concatenates them vertically.
A matrix is a two-dimensional, rectangular array of data elements arranged in rows and columns. The elements can be numbers, logical values (true or false), dates and times, strings, or some other MATLAB data type. Even a single number is stored as a matrix.
Mar 2, 2021 · I have 50 1111 x 3 size matrics. I want to combine them into one final matrix such as all first rows from individual matrices are in first 50 rows and then all 2nd rows and so on. Also, for each set of rows it should insert a header row at the beginning.
