Index exceeds the number of array elements

Hello, matlab shows me this problem:

Index exceeds the number of array elements (495).

Error in Untitled22222 (line 34)

if suma(i)== 0

I mean exactly this loop, I got a little lost and I don't know what to do next.

while 1
    if suma(i)== 0
        p_kolumna=i;
        break;
    end
    i=i+1;
end

Thank you for your help

What is suma function?

[Awais Saeed]

It seems that your condidtion did not meet because of which while loop still runs with an increment of i and i becomes greater than the largest index available.

[Blazej Staniak]

ok how should i improve it?

[Awais Saeed]

if summa(i) is something like 0.000000000000456, the condition will never meet. Use

format long

to see the output

You should share complete code to get help. The variables are not know in the given snippet.

Replace the while loop condition:

while 1

with

while i<=length(suma)

It eill not give the error..but still I am surprised what for this while loop is.

[Blazej Staniak]

yes it is working but i have outher problem...

Unrecognized function or variable 'p_kolumna'.

Error in Untitled (line 38)

im = imcrop(im, [p_kolumna, 1, kolumna, wiersz]);

[KSSV]

It is becuase p_kolumna is not defined....the suma(i) was never equal to zero. You are missing some logic in your problem.

[Blazej Staniak]

p_kolumna is definded in the loop, how to repair?

[KSSV]

It is defined... But in the while loop suma will never be zero and it will never take the defined value. What is your problem exactly?
