A matrix has rows and columns; when we want to multiply 2 matrices, the number of columns and rows matters for it to be possible. We describe matrices to their rows and columns, e.g., a 2 x 4 matrix has 2 rows and 4 columns. With all this information, the first matrix’s(left ...
Finally, you are printing arr_2 to verify that it is a 2x2 array. Now you should see what happens when you change a value in arr_2. Like in the MATLAB example, you should change the upper left element of arr_2: Python In [5]: arr_2[0, 0] = 10 In [6]: arr_2 Out[6]...
If you're getting real eigenvectors right now, one way to obtain a complex ones is to multiply them by i=sqrt(-1). Remember that if v is an eigenvector, then so is c*v for any scalar, c, real or complex. Anas A.Salam el 30 de Mzo. de 2013 thank you so much :)...
