Exercises

Ex. 1 → Consider a 4 × 3 matrix M:

1. Construct this matrix in Python using the function array .
2. Construct the same matrix using the function arange  followed by a suitable reshape.
3. What is the result of the expression M[2,:] ? What is the result of the similar expression M[2:]?

Ex. 2 → Given a vector x, construct in Python the following matrix:

                 

Here, x_i are the components of the vector x (numbered from zero). Given a vector y, solve in Python the linear equation system Va = y. Let the components of a be denoted by a_i, i = ...
