Hi Everybody

I have the following simple script:

if P(1) == 0
return;
else
P1=P(1)

if P(2) == 0
return;
else
P2=P(2)

if P(3) == 0
return;
else
P3=P(3)
end
end
end

If i don't have any value at any location of the matrix or if the
value is "0" then i want the program to stop executing.

Suppose i have

P=[1,2 ];

Here i have only two values for P(1) and P(2) so when i execute script
then i get the following error:

??? Attempted to access P(3); index out of bounds because numel(P)=2.

Error in ==> p at 13
if P(3) == 0

Any help in this regard is highly appreciated.

Regards

Could you please structure better your script?

Hi

I am writing it again. The script is:

if P(1) == 0
return;
else
P1=P(1)

if P(2) == 0
return;
else
P2=P(2)

if P(3) == 0
return;
else
P3=P(3)
end
end
end

Sorry for the previous post. I am going to rewrite it again:

if P(1) == 0
return;
else
P1=P(1);

if P(2) == 0
return;
else
P2=P(2)

if P(3) == 0
return;
else
P3=P(3)
end

end

end


When i give it the following vector as input:

P=[1,2 ];

I get the following error:

??? Attempted to access P(3); index out of bounds because numel(P)=2.

Error in ==> p at 13
if P(3) == 0


Thank you for your response.

Hi Virtualized,

Here is your code:

P=[1,2];

if P(1) == 0
return;
else
P1=P(1);

if P(2) == 0
return;
else
P2=P(2);

if P(3) == 0 %problem in this line
return;
else
P3=P(3);
end
end
end

Your problem is in the line 13, there you are asking a question to computer: is P(3) equal to 0? However you don't have in your matrix any value in that position, therefore the computer doesn't have any number to compare... and that's why you have the error...

If you change your matrix P to P=[1,2,3], you'll not have any problem...
