WebTime for action – computing Fibonacci numbers. The Fibonacci recurrence relation can be represented by a matrix. Calculation of Fibonacci numbers can be expressed as repeated matrix multiplication: Create the Fibonacci matrix as follows: F = np.matrix ( [ [1, 1], [1, 0]]) print "F", F. Copy. The Fibonacci matrix appears as follows: WebHere, we store the number of terms in nterms.We initialize the first term to 0 and the second term to 1. If the number of terms is more than 2, we use a while loop to find the next term in the sequence by adding the preceding two terms. We then interchange the variables (update it) and continue on with the process.
