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. Sep 5, 2023 · 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). So this is the code I have written. Everything works fine except for the two min- functions. When I run the code I get the message "Array indices must be positive integers or logical values.". I have searched the internet for answers but no solution seems to be the one for me. Anyone know what might be the problem? Thank you :)Index in position 1 is invalid.
