Array indices must be positive integers or logical values.
2. You have apparently created a variable ylim at some point in your code, which has replaced the ylim function in MATLAB. Type clear ylim in your command window and try again. If you still get the same error, inspect your code. You have likely named one of your variable ylim (look for ylim=...). Hi everyone, i hope someone can help.
The section of code with n(p/0.01) also looks like it might be missing a multiplication operator. If it isn't and you intended p/0.01 to give you an integer value you can use as an index into n, you may encounter difficulties due to floating point arithmetic.Index in position 1 is invalid. Array indices must be positive integers or logical values.This is a simple for loop where we iterate through a range of numbers. This would be fine in theory. But what if y had a value of 0.6?

Accepted Answer. They're not meant to be empty. Going up we see, [V,I] = min ( [Va,Vd], [],2); It's the colum index where a minimum is found. I don't know what Va and Vd are. if they are column vectors then [Va, Vd] only has two columns, and obviously, you're never going to find a minimum in the 3rd column.Array indices must be positive integers or logical values.

In programming, writing f(x) = x^2 + 1 would typically be understood as using indexing notation -- that the current numeric value of x is to be looked up, x^2 + 1 calculated, and the result to be stored in vector f indexed at the locations whose offset is in x. But your x (n in your case) values are not integers, and not many programming languages allow …
