The code is not working.

@Walter Roberson, thanks for the question. If for instance any of the conditions are met, maybe app.HSV = 3, and app.tcof = 30000, the error will indicate on that particular line of code. If its another line meet the condition, the error didplay on the particular line that meet the condition and so on. I have tried for loop and while statements I dont know why it has refused to work.

app.HSV =0:15; % app.HSV
app.tcof = 0:400000;
app.invf =0:1;
are all vectors, not scalars. Short circuit operators only operate on scalar quantities is what is triggering the error message.
>> app.HSV =0:15;
>> app.HSV > 0 && app.HSV <= 4
Operands to the || and && operators must be convertible to logical scalar values.
>> app.HSV > 0 & app.HSV <= 4
ans =
1×16 logical array
0 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0

Thanks, when I test the codes based on DB suggestion in command window, it is working and returning the right result to the placeholder. But wouldn't display on appdesgner "numeric edit field" that suppose to hold the result based on the conditions. It doesnt indicate any syntax error, Just bypassing all the test fields to display the last line which is: " Result out of Range".
Time to use the debugger. Put a breakpoint in just after the numeric field is retrieved, examine it, and then start single-stepping until you find the problem.
