MATLAB: Do I get this error? If i do it in the command window it seems to be possible

errorMATLAB

Hi everybody, I have a similar problem and I have absolutely no clue where my mistake is. I get the same error but I don´t see why. I am a beginner at Matlab from germany sitting on my bachelor thesis. WIthin the project my goal is to check whether the point is sitting in a bounding box. Therefor I check the first box, which is described by the 8 Points on the Matrix M, with all the 8 points of my component. I then move on to the next box and so on. However if I go into the second box, I get the following error:

This is my Code or at least the part I think is relevant:

Please help me as I said I´m just getting started, so it´s possible I misunderstood something completely.

Thanks a lot guys,

Johnny

Inside a for loop, you are assigning

M = M{INDEX}

That replaces all of M with the contents of one cell of M. Afterwards, M is unlikely to be a cell array.

MATLAB: Error –> Brace indexing is not supported for variables of this type.

What the error message means is simple, you cannot use {} to index your GroupingValue_1 because for that type of variable, {} indexing has no meaning.

It looks like your code is expecting GroupingVariable to be a cell array. It is not. You'll have to find earlier in your code why that is not the case.

MATLAB: True or false to elements of a cell array

Hi, I understand you are getting some problem with your code. The error is due to these following reasons.

In the Line

    if inside{allepunkte}{huellkoerper}==true & outside{allepunkte}{huellkoerper}==true

The inside is a 1D cell array of size 1x8, but the code treats it as a 2D cell array.

2. There is an undeclared variable 'verschz' in the code.

After resolving these following issues the code should work.

Note: In the following Lines

            if inside{allepunkte}{huellkoerper}==true & outside{allepunkte}{huellkoerper}==true
                %hier wird nun ermittelt in welchen er wohl verschoben werden soll,
                %mit anderen Worten: Welcher Körper liegt dem Punkt am nächsten
            else

There is nothing inside the if statement. You can consider modifying this codition. I have attached the modified code.
