WebSep 17, 2024 · You can access a particular scalar in your Python object using its index. Remember that Python index starts counting at zero. For example, to get the fourth element in f and b vectors, we would use the following syntax: xxxxxxxxxx print(f[3]) print(b[3]) run restart restart & run all 5 16 WebBasically this method is described as "square and multiply" for exponentiation (which works just the same way with squaring instead of doubling and multiplying instead of adding). In your example: Let's transform your number 57 into a binary number F and address its digits as F [ i]. T := P; S := 0 for all i : if F [ i] == 1: S + = T T := 2T WebJan 5, 2024 · Matrix multiplication. Matrix multiplication is a more interesting case, because you can multiply a matrix by another matrix, or alternatively you can multiply it by a scalar (ie an ordinary number).
