Store m iterations of a variable in for loop

clear all; clc; close all;

%generate random values for VN, VE, VD in vector form

VN_random = randi(100,10,1);%(feet/second)north velocity (column vector of random velocities)

VE_random = randi(100,10,1);%(feet/second)east velocity

VD_random = randi(20,10,1);%(feet/second)down velocity

%generate random velocities for position extrapolation

%initial velocity

m = 10;

for i = 1:m

VN_array(i) = VN_random(i) %array of n random numbers

VE_array(i) = VE_random(i) %array of n random numbers

VD_array(i) = VD_random(i) %array of n random numbers

end

VN_array = VN_array'

VE_array = VE_array'

VD_array = VD_array'

%generate m iterations of LAT_3,LON_3,ALT_3

step = 1

m = 10

for array = i:step:m

%initial velocity

VN = VN_array(i);%(feet/second)north velocity

%VE = 0 ;%(feet/second)east velocity

%VD = 0 ;%(feet/second)down velocity

%call position extrapolation function

%[LAT_3,LON_3,ALT_3] = Position_Extrapolation(t_0,t_final,VN,VE,VD,LAT,LON,ALT)

[LAT_3,LON_3,ALT_3] = Position_Extrapolation(0,100,VN,0,0,pi/4,pi/4,10)

end

Above is an attached piece of code that generates the outputs LAT_3, LON_3 and ALT_3. These outputs (which are part of a function I called in the script (Posittion Extrapolation) are located inside of a for loop, which is designed to run the function through m iterations of the variable VN. The variable VN is an input variable of the function that I am attempting to run through the function m times and store these values as an array. How would I go about running the variable "VN" m times (as created by the random number generator) through the function "Position Extrapolation" and store them in an array?

Perhaps as follows:

ivals=1:step:m;

J=numel(ivals);

[LAT_3,LON_3,ALT_3]=deal(nan(1,J));

for j = 1:J
    
    i=ivals(j);
    
 [LAT_3(i),LON_3(i),ALT_3(i)] = Position_Extrapolation(0,100,VN_array(i),0,0,pi/4,pi/4,10);
 
 
end

Looks good. Thanks man. I appreicate it. I'll have to research some of these functions for future refernce, to better understand how you constructed this code
