For context I'm developing a basic car speed controller, in which I'm using the changes in altitude to determine a slope which will slow down the car. The controller will speed up the car when it is under the desired speed.
I have defined functions as matrix of (1,instances) many different different parameters, one of which is pressure
I am trying to define pressure as a function of altitude , with altitude being a matrix (1,n) of the following type:
altitude = [a,a,a,a,a,b,c,d,e,f,g,h,iiiiii]
and then I tried to calculate the pressure matrix as function of the altitude in each point as well as the difference in pressure between each step:
but when I plot the pressure as function of altitude I get a downwards slope when I'm pretty sure I should be getting a quadratic
additionally the dp matrix should resemble a derivative of the pressure matrix and it is constant throughout time.
As I said I'm a begginer and perhaps this is not the best method for relating parameters with one another, so I'm open to suggestions.
Additionally I have no idea why it doesn't work so If somebody could clear it up for me I would appreciate it!
Thank you in advance
