Создал графический интерфейс в QtDesigner и у меня есть условный файл design.ui. Также есть основной код который подсчитывает матрицу методом Крамера или Гауса. Искал в интернете разные гайды не нашел толкового объяснения как код и интерфейс засунуть в .exe вместе.
Код программы:

Form, _ = uic.loadUiType("2.ui")

n = len(b)
for i in range(n):
if A[i][i] == 0:
return None
for j in range(i+1, n):
k = A[j][i] / A[i][i]
for l in range(i, n):
A[j][l] -= k * A[i][l]
b[j] -= k * b[i]
x = [0] * n
for i in range(n-1, -1, -1):
s = 0
for j in range(i+1, n):
s += A[i][j] * x[j]
x[i] = (b[i] - s) / A[i][i]
