How can I make a function that calculates the values of the linear interpolation function f(x) = a.x + b for an interval of x values given by Xl = [xmin,xmax] where n >= 1 is the number of intervals into which the interval Xl will be divided?

Hi Ihor,

As per my understanding, if given minimum and maximum values of x, you are interested in finding the linear interpolation. Please find the following function code for your reference,

function interpolated_values = linear_interpolation(xmin, xmax, a, b) 
    N = 1000; 
    x = linspace(xmin, xmax, N); 
    interpolated_values = a*x + b; 
end
