###### How to check if character is upper or lowercase in Fortran?

rigel2022-08-15

Within Fortran, what are the library functions, if any (I'm using gfortran 11) that return whether the character is upper or lower case? character :: c
c = 'l'
print *, is_lower(c) ! should display 'T'
print *, is_upper(c) ! should display 'F'
c = 'L

I have the following expression multiplying two expressions: from sympy import *
c1, c2, x = symbols("c1, c2, x")
expr = c2*x*(c1*x + c2*x)
I would like to be able to open the parenthesis, so that this expression would be c1*c2*x**2 + c2**2*x**2

Hello python community, I am new to python and playing around with numpy arrays and have a question. E.g. I have this 3D array (in reality the array is much much bigger) input = np.array([[[0,0,1,1,2,2],[0,0,1,1,2,2],[0,0,1,1,2,2]],[[0,0,1,1,2,2],[0,

I have the following surface import numpy as np
surface = np.zeros((10, 10))
surface[5, 5] = 1
This looks as follows: [0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]
[0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]
[0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]

I was trying to simulate multivariate normal data in python the following way n = 100
p = 10
mu = np.random.normal(loc=0, scale=3, size=p)
A = np.random.uniform(low = -4, high = 4, size = (p, 1))
A = pd.DataFrame(A)
Sigma = np.dot(A, np.transpose(A))
