How to increment the specific command

Par.Instr{5}.Obj.Write(['SOURce' num2str(lineNum) ':VOLTage:OFFSet ' num2str( Par.SigGen{lineNum}.PulseAmp)])

I need to increment the value of Par.SigGen{lineNum}.PulseAmp in the above code and I am calling the values from excel sheet like 4:0.1:5

When I run the above code its just take first value ie 4. How to make a cycle for 4,4.1,4.2....5?

Thank you.

Akshay - can't you just use a for loop like

 for k=4:0.1:5
    % do something
 end

In the above we iterate from 4 to 5 with a step size (increment) of 0.1.

A for-loop can be used, such as

for lineNum=4:0.1:5
num2str(lineNum)
end

But the "lineNum" in Par.SigGen{lineNum}.PulseAmp seems to be an index. It needs to be a non-zero integer such as 1, 2, 3. It can not be a decimal number such as 4.1, 4.2 etc.
