Using Matlab 2019, please solve this.

1) Write a program to calculate the Fibonacci series up to the 10th term. 2) Write a program to get 10 inputs from the keyboard and calculate the variance of those numbers. 3) Write a program to get 10 number from the keyboard and save them in a MAT file. a) Read the .MAT file and sum all positive numbers. b) Send the output to the screen. 4) Write a function that accepts two complex numbers as input, and outputs the multiplication result in polar form. 5) Write a function that accepts the coefficients of a polynomial along with the degree of polynomial and calculates the differentiation coefficients of that polynomial. 5. Bonus) output the differentiation in a standard form rather just the coefficients. Example: the inputs are (3, 2, 1, 6), then output will be dy(x) = 9x2 + 4x +1. 6) Write a function to get two inputs a, b and generates output y as below: {a? +62 Tal > 161 y = lal = 161 (a + b, lal
