When you take physical systems, and model them with mathematical models, computers will process the data as mathematical arrays. In a physical system, the transforming function is usually a process, while in virtual reality, the transforming function is an algorithm. The intermediary in the conversion, is known as the transforming function. Whether youвЂ™re an electrical engineer designing a motherboard, or a process control engineer designing a control system to manage system disturbances, or a biological engineer detecting whether or not feeding a fungus specie A will produce the desired synthesized chemical product, at some point youвЂ™ll be exposed to systems that take a feed, and produce a different outcome. Over time, modelling any scientific and engineering system will be the norm for any mathematics, science or engineering base.

Brief Tutorial: MATLAB Reshape Introduction to Reshape Array.

The MATLAB Reshape Array, is one tool that facilitates the mathematical manipulation of these virtual systems. In the advanced scientific sphere, there is often a transition from viewing systems as physical representations, to the view of those systems as their mathematical virtual twins. Nature designs in such a manner, so naturally across the sciences the odds of encountering an input-output process are highly likely. Here we discuss the uses of MATLAB, what is 3 D Matrix? andВ how to create 3D arrays in MATLAB and also some manipulations on them.There comes a time in every scientist and engineerвЂ™s life when all you live and breathe are input and output processes. The output that we will get will have rows and columns interchanged as follows: i.e., changing rows with columns or vice versa. We can use this function if we want to rearrange the dimensions of the matrics. The same thing is then done for 2nd page 2. This will create a 2D matrix with 6 rows and 5 columns:ДЄs you can notice, RESHAPE will work column-wise, so first all the elements of A take along the column, for the first page. This is useful mainly during visualization of dataДЇor Example:В Create a 6*5 matrics using two 3*5 matrices MATLAB provides us with a couple of functions to manipulate the elements of a multidimensional array. Now, access = A(2,3,1) will give us 0 as output Functions to manipulate the elements of a Multidimensional Array To demonstrate this, letвЂ™s use the 3D matrix A which we used above, So, 2,3,1 element of a 3D Matrix will be the element present at 2nd row, 3rd column of the 1st page To do this simply use subscripts as integers. How can we access the elements of the array?

So to extend our above example, we will simply give,Д«(:,:,4) = and output will be: 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.ДЇor Example:В 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).LetвЂ™s now understand how can we create a 3D Matrix in MATLABДЇor a 3-dimensional array, create a 2D matrix first and then extend it to a 3D matrix. Here element (2,1,1) represents вЂRowвЂ™ number 2 вЂColumnвЂ™ number one and вЂPageвЂ™ number 1. The third subscript in a 3D Matrix is used to represent the sheets or pages of an element.Д®.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?ДЈ-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.Д®ach element has two subscripts one is the row index and the other is the column index.Д®.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.
