Possibly your left-hand-side index i is also unallowed, but if you've set that one to a positive integer then it's OK (I've stopped use i and j as indices - sooner or later one tend to use them for their purpose of the imaginary 1i. . Instead I use i1, i2 and j1 etc for ...Nov 20, 2022 · yes you're correct,but i 'am still facing a problem to put this into code. what my intension is, I want to subtract two matrices which are not of the same order though. my first matrix T is of order 101 by 101 and the other one A is 1001 by 1001 and i want the resultant matrix E_epsilon to be of order 101 by 101. 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?Incidentally, a better way to find the max over an array is max(CCC(:)) or in recent Matlab max(CCC,[],'all'). These work independently of the dimension of the array, and are more efficient because you only call max() one time.

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.It's not that Matlab doesn't know what i is, assuming it's not defined by the user. It's that i takes on the value of the imaginary unit when not otherwise defined.Nov 26, 2020 · Array indices must be positive integers or logical values. Follow 233 views (last 30 days) ... Array indices must be positive integers or logical values. Array indices must be positive integers or logical values. The most robust solution would be to create a vector M, and then have your for loop loop through each element of M, with the loop counter being used assign the result to u .

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.

Nov 20, 2019 · I just copied and pasted your code ( and I cleared the workspace) and the code runs but it just gives back y= [0 0 0 0 0 0 0 ]. Only the first two elements should be 0 (initial y was given as 0 and 2nd y returns as 0) but element 3 should be 0.04, element 4 0.128 then 0.2736 and then 0.48832 for the final element.

1 Answer. Please provide a minimal reproducible example. Nevertheless, my guess is that index "k" or "framecito" are starting at value 0 or receiving some non-integer value, when vectors and arrays in MATLALB only have positive integer positions (ie.: Frame (1), Frame (2), Frame (3) or Histograma_acum_norm (1), …1 Answer Sorted by: 2 Here is a minimal example demonstrating your problem: for i=1:10 clear jpgfiles=rand (10,1); %some dummy data to replace your actual code jpgfiles (i); end the clear deletes the variable i which means i is the imaginary unit, not a valid index.
