![]() Making a skew-symmetric matrix from a vector is not something most people will ever need to do, so it is unlikely you would find a simple command to do it. In MATLAB, clear command clears all the variables of the workspace. A great virtue of MATLAB (ok, almost any programming language) is the ability to write functions that do what you want. MATLAB VIEW – to show whos command executionīefore executing whos command, variables are listed in Workspace as shown belowĪfter executing the whos command, variables name, size, bytes, class, attributes displayed in the command window as shown below MATLAB clear command Whos displays a list of the variables currently in the memory and their sizes together with information about their bytes and class. n norm (X,p) returns the p -norm of matrix X, where p is 1, 2, or Inf: If p 1, then n is the maximum. n norm (X) returns the 2-norm or maximum singular value of matrix X, which is approximately max (svd (X)). n norm (v,p) returns the generalized vector p -norm. ![]() If you compare a 1-by-N row vector to an M-by-1 column vector, then MATLAB expands each vector into an M-by-N matrix before performing the comparison. MATLAB VIEW – to show who command executionīefore executing who command, variables are listed in Workspace as shown belowĪfter executing who command, variables name displayed in the command window as shown below MATLAB whos command This norm is also called the 2-norm, vector magnitude, or Euclidean length. For example, if you compare two matrices of the same size, then the result is a logical matrix of the same size with elements indicating where the relation is true. Who displays a list of the variables currently in the memory. When these commands typed in the Command Window and the Enter key is pressed, either they provide information, or they perform a task as specified below. MATLAB – Proper commands for managing variablesĬommands like clear, who and whos, that can be used to eliminate variables or to obtain information about variables that have been created. I am wondering of there is a way that enables me to insert a column vector in a matrix (similar to insert column in excel) without replacing any existing column. Type the following code in the command window and see the result– The main reason for this tutorial is to explain the basics of using vectorizing syntax in MATLAB. ![]() Type the following code in the command window and see the result –Īim (1): To define variable x as a matrix and the elements of x are given by: x=(1, 22, 3, 2, 34, 4, 12, 2, 4).ġ2 2 4 MATLAB VIEW – Program (1) and Output (1): Output (1): x = 1 22 3 MATLAB VIEW – Program (1) and Output (1):
