Building Function for Percentage

Hello. For my client, want to build function in Matlab for 1 scaler input (speed limit for circuit) and 1 scaler input (speed of some signals around circuit).

Answer 1

[David Hill]

function pD = percentDiff(limit,speedM)
pD=100*(speedM-limit)/limit;
end

Not sure what you want for good percentage difference. Do you want 'good' to be <limit (negative %diff) or <-valve? Then,

function [pD,tf] = percentDiff(limit,speedM,value)
pD=100*(speedM-limit)/limit;
tf=pD<-value;%good would be value of 1 in the tf vector
end

Hello David.

For pD, why do you write SpeedM? I confirm this is the speed of more than 1 signal in the circuit? It is not the speed for just 1 signal but a group of signals? Is that possible?

What does tf mean in your example?

[David Hill]

Yes, it is a vector
