sum( myImage == someValue );
in the absence of any substantive information on what you are counting them in!

Depending on that you wanna count (one or more values) you can use this:
VALS=[1,2...N] % Array of values 1xN
thermIm= % Matrix of thermal image values
noVals=sum(sum(ismember(thermIm,VALS)))
noVals is the amount of pixels in thermal image containing the values stored in array VALS
If you have just one value you can just use a combination of "length" and "find"
VAL= % Random number 1x1
noVals=length(find(thermIm==VAL))

You can take a histogram:
histObject = histogram(yourImage);
or
[counts, grayLevels] = imhist(grayImage);
