How to write this fuction in Matlab?
Someone wrote it in Python like this:
def b(r):
return b_1 - (b_1 - b_2) / (r_2 - r_1) * (r - r_1)

Assuming that b_1, b_2, r_1, r_2 are constants:
% As anonymous function:
r_1 = rand; % Define the constants
r_2 = rand;
b_1 = rand;
b_2 = rand;
b = @(r) b_1 - (b_1 - b_2) / (r_2 - r_1) * (r - r_1);
% Or as a function:
function out = b(r)
r_1 = rand; % Define the constants
r_2 = rand;
b_1 = rand;
b_2 = rand;
out = b_1 - (b_1 - b_2) / (r_2 - r_1) * (r - r_1);
end

Hi, your function contains four parameters, so the python code is incomplete. You can do this several ways in MATLAB, classic syntax would be:
% Test call
myVar = bFunName(10)
myVar = -5
% function definition
function b = bFunName(r)
b_1 = 1;
b_2 = 2;
r_2 = 3;
r_1 = 4;
b = b_1 - (b_1 - b_2) / (r_2 - r_1) * (r - r_1);
end

b= @(r) b1 - ((b1-b2)*(r-r1))/(r2 -r1);
where b1,b2,r1,r2 are constants
