Assigning NaN to certain values

Hello,

I am trying to read nc file and it contains values (-177.6600, -177.6500, -177.6300, -177.5900, -177.5700). I want to assign NaN to all these values (there is a huge number of these values).I tried the following code but it didn't remove the maximum value i.e., -177.5700.

Temp = ncread('G\01.06.17\NC_H08_20170601_0500_L2CLP010_FLDK.02401_02401.nc', 'Temperature'); 
Temp(Temp<=-177.5700)= NaN;

Kindly help.

Thank you.

What have you tried is correct. What made you to tell that the value is not replaced with NaN? What is size of Temp?

Size of temp is 2401*2401

This is the result after running code. -177.5700 values are still present.

Try:

tol = 10^-3 ; 
Temp(Temp<=-(177.5700+tol))= NaN;

Unfortunately, It didn't work.

You might try rounding to 4 decimal places first

Temp=round(Temp,4);
Temp(ismember(Temp,[-177.6600, -177.6500, -177.6300, -177.5900, -177.5700]))=nan;

Thanks David!. It tried using your lines of code and it worked.

A slightly more simple approach:

Temp(round(Temp,4)<=-177.57)= NaN;

Thank you!
