MATLAB: Determine whether or not an array of six is changing from live data collection

arraychangefor loopfunctionslive data

Hello All:

I am currently trying to write code that would determine whether or not live data, in the form of an array of six, is changing its values. The data is being collected by sensors so thus far I have attempted to create a function…but can't get this part down. So my question is how would Determine whether or not an array of six is changing from live data collection? if you need more data to be able to answer the question please let me know. Thank you ALL!

if isequal(olddata, newdata) then either the data has not changed or else it changed to exactly the same value it was before.

No, you do not need hold. You can modify the example you find in help polar.

Your function is not the problem. You’re not calling it correctly, and you’re not using the correct solver.

Call it this way instead, and it works:

icv = ones(6,1);                                        % <== CHANGE TO APPROPRIATE INITIAL CONDITIONS
t0 = 0; tf = 2E-2; 
TSPAN = linspace(t0, tf, 150);
[T,Y] = ode15s(@rate_eq2,TSPAN,icv);
figure(1)
plot(T, Y)
grid
legend('6','5','4','3','2','1', 'Location','E')
title('Population different levels')

The ‘icv’ assignment are the initial conditions vector. If they’re all initially zero, then the solution is zero, so at least some of them have to be non-zero. You were also confusing the initial conditions and the time span arguments.
