As you can see based on the previously shown RStudio console output, our data matrix consists of five rows and three columns. The rows are named alphabetically and the variables are named x1, x2, and x3. In the following example, I’ll show how totranspose(i.e. rotate) this data tab...

returns (bool) − If the input matrix is symmetric it returns True, otherwise False.Example 1In the below code we have created two matrices a, b. Where a is symmetric because it is equal to its transpose a[1,0]=a[0,1] but it is not in the case of bOpen Compiler from scipy....

numpy.ravel(a, order='C') Parameters: Return value: y : array_like - y is an array of the same subtype as a, with shape (a.size,). Note that matrices are special cased for backward compatibility, if a is a matrix, then y is a 1-D ndarray. ...
However, it seems that I shouldn't use diag function in my code. How can I do that? Is there any other way to do the same thing without using any Matlab built-in functions? Thanks functionx1 = axb(A,b,e) %This function takes the matrix of coefficients A and the vector b and the...
