KUIS (14 Oktober 2019)
1. Problem Set 2.1 No. 6 hal. 55
Solve the equations Ax = b by Gauss elimination, where
A =[[0, 0, 2, 1, 2], [0, 1, 0, 2, -1], [1, 2, 0, -2, 0], [0, 0, 0, -1, 1], [0, 1, -1, 1, -1]]
B =[1, 1, -4, -2, -1]
Matrix dikonfigurasi ulang
A = [[1, 2, 0, -2, 0], [0, 1, 0, 2, -1],[0, 1, -1, 1, -1], [0, 0, 0, -1, 1], [0, 0, 2, 1, 2]]
B = [-4, 1, -1, -2, 1]
Hasil operasi matrix
X1 = 2
X2 = -2
X3 = 1
X4 = 1
X5 = -1
Python
import numpy as np
- 1. define matrix
A = np.array ([[0, 0, 2, 1, 2], [0, 1, 0, 2, -1],[1, 2, 0, -2, 0], [0, 0, 0, -1, 1], [0, 1, -1, 1, -1]], float) B = np.array ([[1], [1],[-4], [-2], [-1]], float)
n=len(A)
- 2. eliminasi gauss
for k in range (0,n-1):
for i in range (k+1, n): if A[i,k]! = 0 : lam = A [i, k] / A [k, k] A [i, k : n] = A [i, k : n] - ( A [k, k : n] * lam) B[i] = B[i] - (B[k]*lam)
print ('matrix A:', '\n', A) print ('matrix B:', '\n', B)
- 3. back subtitution
x = np.zeros(n,float) for m in range (n-1, -1, -1):
x[m]=(B[m]-np.dot(A[m, m+1:n], x[m+1:n]))/A[m,m] print ('nilai X', m+1, '=', x[m])
2. Problem Set 7.1 No. 1 hal. 263
import numpy as np
def diff_y (x,y):
fungsi = x**2 - 4*y return (fungsi)
x = 0 y = 1 h = 0.01 step_size = np.range (0,0.03,h)
for t in step_size:
k1 = diff_y (x,y) k2 = diff_y ((x+0.5h),(y+0.05*k1*h)
y = y + k1*h
print ('maka y(0.03) adalah', y)
