The array is long enough, still gets Array Index out of bound error.

I have a structure array named AnalysisResult. Each of the structure have three elements.

• width which is a 216 x 2 x 14 Matrix,
• width_mean which is a 1 x 14 vector
• width_std which is a 1 x 14 vector

when I run the following code

function [acrossAxisRadiusVariation,acrossAxisMeanVariation] = calculateVariationAcrossAxis(AnalysisResult,circleNo,angleNo) 
ss=size(AnalysisResult,2);
acrossAxisRadiusVariation=zeros(ss,1);
for counter=1:ss
    acrossAxisRadiusVariation(counter,:)=AnalysisResult(counter).width(angleNo,2,circleNo);
    acrossAxisMeanVariation(counter,:)=AnalysisResult(counter).width_mean(circleNo);
end

end

If my structure have 100 around elements, with circleNo =13 and angleNo = 54 it works fine. but if I run for circleNo=14. It gives me following error.

Attempted to access AnalysisResult.width(54,2,14); index out of bounds because size(AnalysisResult.width)=[126,2,13].

Error in calculateVariationAcrossAxis (line 7)
    acrossAxisRadiusVariation(counter,:)=AnalysisResult(counter).width(angleNo,2,circleNo);

But on command window I am able to access AnalysisResult(1).width(54,2,14).

If my structure have 700 elements then the similar problem occurs for circleNo 8 and above.

Is this something to do with the size of the parameters.

I am not able to figure out.

Put this in your loop:

for counter=1:ss
    disp(size(AnalysisResult(counter).width))
    ... etc
end

and tell us what is displays just before the error occurs.

Got the answer as I added the line disp(size(AnalysisResult(counter).width)) and found that for some of the values of counter this is 13 for some it also gets 12 so there was a problem in generation of the width matrix. Thank you all.
