MATLAB Tutorials class 4: MATLAB command  diag, det, trace               We discussed random number generation in my previous post (rand, randi,randn function). We're going to see some interesting Matlab commands and their functions in this post. They are diag,det, and trace. First, we going to see about diag diag           By using the diag command we can create a diagonal matrix and can compute the diagonal of the matrix. Diagonal elements are one in the identity matrix(eye), but we can create our desired diagonal element by using the diag command. This is the major difference between the diagonal matrix (diag) and the identity matrix (eye). 1. How to create a diagonal matrix in MATLAB?           The syntax for creating a diagonal matrix in MATLAB is                 diag_creation=diag([1 2 3 4 5]) >> diag_creation=diag(...

MATLAB Tutorials Class3: How to Generate a  random number in MATLAB Hai... We addressed the creation of an array and matrix in my previous post . We will see how to generate a random number in MATLAB here.  1. How to generate uniformly distributed random numbers in MATLAB? Syntax is                           rand_val_creation=rand() The uniformly distributed number 0 to 1 range is generated by the rand function. We can create a random matrix, just like the creation of zeros and one's matrix.  Case 1:if we give syntax like 'rand' means it creates 1 x 1 rand matrix range between 0 to 1. >> rand_no_creation=rand rand_no_creation =     0.8147 Case 2: If we mention a number, that number is considered to be a row and column count. >> rand_no_creation=rand(4) rand_no_creation =     0.9058    0.0975    0.9649    0.4854     0.1270...

 MATLAB Tutorials Class 2:  Creation of  Matrix and array in  MATLAB  Hai... We addressed the environmental setup and layout configuration in my previous post . Here we going to see Matrix and array. The expansion of MATLAB is the 'Matrix laboratory'. MATLAB script operations are based on matrix and array. 1. What is the Matrix?           The matrix is a framework for the number of columns and rows. The matrix may look rectangular or square. A count of rows and columns is used for matrix status representation ( no. of. row X no. of. column matrix). For instance, if the number of rows and columns is 3, the matrix is known as the 3 x 3 matrix.  2. What is an array?          An array is an arrangement of elements together in a single row.   3. How to create an  array  in MATLAB? To do this, you can use the command window. For execution, after entering the code line, give enter. If you want t...

  MATLAB tutorials class 1: Environmental setup and layout configuration in MATLAB                Hai... We are going to discuss the environmental setup in MATLAB in this post. We need to know who invented the MATLAB tool before going to see the basics first. He's Cleve Moler. In 1981, MATLAB was originally designed by Cleve Moler as a calculator function with 71 reserved commands. Matlab wasn't used as a programming language at that time. TABLE 1 represents that 71 reserved command. Table 1.
