In this article we discuss xnxn matrix matlab plot algorithm and xnxn matrix matlab code. In other words, we will first see how to create a matrix in matlab. Then we will see how we can create a graph from this matrix. Finally we will discuss some advanced functions with matlab.
Example with 3x3x3 matrix in matlab
First, in this example I am using the rand function to generate decimal values in a 3x3x3 matrix. Then I display it in matlab then I create a graph with the plot 3 function on the 3 dimensions of the example matrix.
>> M = rand(3,3,3) M(:,:,1) = 0.8147 0.9134 0.2785 0.9058 0.6324 0.5469 0.1270 0.0975 0.9575 M(:,:,2) = 0.9649 0.9572 0.1419 0.1576 0.4854 0.4218 0.9706 0.8003 0.9157 M(:,:,3) = 0.7922 0.0357 0.6787 0.9595 0.8491 0.7577 0.6557 0.9340 0.7431 >> plot3(M(1,:),M(2,:),M(3,:))
In addition, here is a preview of the graph that is created with this:

Example with 3×3 matrix in matlab with int value
>> M=randi([1,10],3,3) >> plot(M(1,:),M(2,:))

In this example which is similar to the previous one I use the randi function which allows me to generate integers with matlab in a range given as an argument. In the end I get a 3×3 matrix that I display in the console then I use the plot function.
Here is another result if now I use plot3 function :
>> M=randi([1,10],3,3) >> plot3(M(1,:),M(2,:),M(3,:))

About Matrix indexing in Matlab :
Also, in databases, indexing refers to extracting a single data point from a large data set.
The general purpose of an index is to quickly and easily extract values of interest from a database.
MATLAB also allows users to store and retrieve data from databases.
Vector and matrix indexing matlab :
>> A = magic(5) A = 17 24 1 8 15 23 5 7 14 16 4 6 13 20 22 10 12 19 21 3 11 18 25 2 9 >> A(1,:) ans = 17 24 1 8 15 >> A(:,1) ans = 17 23 4 10 11 >> A(3,5) % Extract the element in row 3, column 5 ans = 22 >> A(1:3,2:4) % Extract the vectors ans = 24 1 8 5 7 14 6 13 20 >> A(:,1)

Conclusion – xnxn matrix matlab plot algorithm
In conclusion of this article we had an overview of how to create and make a plot or plot3 of an nxnxn matric in matlab. Also we have seen how the indexing of a matlabe matrix or a vector works. I offer more advanced functions in a following article.
