Write MATLAB function t = pasctri(n) that generates the Pascal triangle t up to the level n.
Remark. Two-dimensional arrays in MATLAB must have the same number of columns in each row. In order to avoid error messages you have to add a certain number of zero entries to the right of last nonzero entry in each row of t but one. This t = pasctri(2).
t =

[solved] – Question 9060
1. The Legendre polynomials Pn(x), n = 0, 1, … are defined recursively as follows
nPn(x) = (2n-1)xPn -1 – (n-1)Pn-2(x), n = 2, 3, … , P0(x) = 1, P1(x) = x
a) Write MATLAB function P = LegendP(n) that takes an integer n (the degree of Pn(x)) and returns its coefficient stored in the descending order of powers.
b) Plot all Legendre polynomials Pn(x), n = 0, 1, …,6 over the interval [-1,1] in one figure.

3. With considering the following algorithm for computing pi:
I. Set a = 1, b = 1/sqrt(2), t = 1/4 and x = 1
II. Repeat the following commands until the difference between a and b is within some desired accuracy:
y = a
a = (a + b)/2
b = sqrt(b*y)
t = t – x*(y – a)^2
x = 2*x
III. From the resulting values of a, b and t, an estimate of pi is
Pi_est = ((a + b)^2)/(4*t)
How many repeats are needed to estimate pi to an accuracy of 1e-8? 1e-15?

[solved] – Question 90691
Carry out the modification, discussed in Exercise 7, to the PARSE program of Chapter 10.
That is, make it possible to parse expressions containing floating-point numbers.
Combine the classes from Exercise 7 with the algorithms from PARSE. You’ll need to
operate on pointers to tokens instead of characters. This involves statements of the kind
Number* ptrN = new Number(ans);
s.push(ptrN);
and
Operator* ptrO = new Operator(ch);
s.push(ptrO);
