Hi

Instead of using a long for loop and if statement, is there alternative method of anylsing a array to on display values which are above or below a certain limit?

For example when sensor is above certain value?

Is there any example

For example i have two arrays

SensorA

And

Temperture.

I would like to find all points in SensorA when temperure is below 30 degrees, and then using that data to preform mean, mode ,etc.

Thanks

I will try that.

At the momment i am using:

temp_ind=find(iot_temperture < 30);
no2_comp =  iot_no2_we_voltage(temp_ind);

And you get an error message ?

Then maybe iot_no2_we_voltage and iot_temperture don't have the same length.

(Shouldn't it be "iot_temperature" instead of "iot_temperture" or did you want to save a character in writing ?)
