Now, if we need to further expand this array, we can simply give the elements of 4th array that we need to add: Here concatenation is being done along with the pages.Argument at first place (3) tells which direction the array needs to be concatenated.We can also use a function called cat Function to create multidimensional arrays.įor Example: Create a 3D array with 3 pages using cat function This can be done by assigning one more 3 by 3 matrix with index value 2 in the third dimension

Create a 3 by 3 matrix as the first page in a 3-D array (you can clearly see that we are first creating a 2D matrix).

Let’s now understand how can we create a 3D Matrix in MATLABįor a 3-dimensional array, create a 2D matrix first and then extend it to a 3D matrix. Here element (2,1,1) represents ‘Row’ number 2 ‘Column’ number one and ‘Page’ number 1. The third subscript in a 3D Matrix is used to represent the sheets or pages of an element.Į.g. As you can guess, they will have 3 subscripts, one subscript along with row and column indexes as for the 2D matrix. What is a 3-D Matrix?ģ-D Matrix is a multidimensional array that is an extension of two-dimensional matrices. (1,1) element here represents Row number is 1 and the column number is 1. You might be already knowing that the dimensions of a 2D matrix are represented by rows and columns.Įach element has two subscripts one is the row index and the other is the column index.Į.g. It is an array in MATLAB which has two or more dimensions. In this article, we will understand multidimensional arrays in MATLAB and, more specifically, 3- dimensional Matrix in Matlab.
