Element Array cell checking

Hi, im trying to create an alogorythm that prevent overlapping block generation in simulink. The intent is for the code to go through each array and compare the 4 points in each generated block for elements and 3points for nodes and check wether the newly generated block overlaps with the previous block. My code below shows my attempt at this:

for  iElements = 1:numel(elementArray) 

    if elementArray(1).yArray{i} == elementArray(2).yArray{i} && elementArray(1).xArray{i} < elementArray(2).xArray{i)
     
        centroidElements = centroidElements{elementArray,:} + abs(elementArray.xArray(1)-elementArray.xArray(2)) + defaultPadding; % if this condition is true, add padding to the centroid
    else
end

elementArray = 1X2 struct

NodeArray = 1X3 struct

centroidELement = 1X2 cell

Im geting the following error when run:

Brace indexing is not supported for variables of this type.

Error in boeing.fuels.tubing.blockPlacement (line 8)

if elementArray(1).yArray{1i} == elementArray(2).yArray{1i}...

Can anyone help me along to get this running?

May I know what is the type of yArray? You can try whos elementArray(1).yArray

[Ikenna Okoye]

This yArray is a reference within the struct of elementArray, so it will be a row vector along with xArray.

If its a row vector, then the indexing should be through () rather than {}. Use elementArray(1).yArray(iElements)
