How to Vertically Concatenate Arrays in MATLAB?

You can vertically concatenate arrays in MATLAB using the vertcat function or the [] operator.

Using vertcat Function

The vertcat function takes two or more arrays as input and stacks them vertically, creating a new array with the combined rows.

Example:

A = [1 2; 3 4];
B = [5 6; 7 8];

C = vertcat(A, B);

disp(C);

Output:

     1     2
     3     4
     5     6
     7     8

Using [] Operator

You can also use the [] operator to concatenate arrays vertically. Simply place the arrays inside the brackets, separated by commas.

Example:

A = [1 2; 3 4];
B = [5 6; 7 8];

C = [A; B];

disp(C);

Output:

     1     2
     3     4
     5     6
     7     8

Practical Insights

• The vertcat function and the [] operator achieve the same result. You can choose whichever method is more convenient for you.
• Ensure that the arrays you are concatenating have the same number of columns. Otherwise, MATLAB will throw an error.
