Array indices must be positive integers or logical values.

Jul 13, 2022 · An index can be any kind of expression, but the value of the expression has to be a positive integer, and it has to be less than or equal to the length of the vector. If it’s zero or negative, you’ll get an error: >> Y(0) Array indices must be positive integers or logical values. If it’s not an integer, you get an error: Subway records 9th consecutive quarter of positive sales, reflecting its successful transformation journey and strategic growth. Subway, one of the world’s largest restaurant brands, has reported its ninth consecutive quarter of positive sa...However, as the 1st values of eta1 and eta2 are zero, the rest of the values will also be zero, as the value of term n is directly proportional to the value of term (n-1) (observed from the formula/expression above).I don't know what the value of that expression is because most of those variables are undefined, but given that deltaT is a scalar variable, I would guess that indexing it like that is not what you mean to be doing.

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.

In these lines f_m appears to be an array intended to hold values: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.and there you are using the 2D array as indices -- but because of the mistake in the if test, you failed to reject the case where at least one value was 0 but not all of the values were 0. So you potentially have 0 as a subscript, which is not permitted.I wanted to make a function y, that has different values at y(0) and same for diff(y(0)), I thought that if I define the function first and then tell it that at some point it is equal as the value of the array(i), it would take that value as the t=0. With this I wanted to solve one differential equation, with 3 different starting conditions.

It does not matter that you WANT V (0) to be something. MATLAB does not support zero based indexing. PERIOD. However, nothing stops you from starting the vector at V (1). And then when you index into the vector, just use V (ind + 1). Now when ind == 0, there is no problem. If you want to do a plot?ERROR: Array indices must be positive integers or logical values.
