Dear all, for the first array I can get ten 2x2matrices (and I am partially happy for this). Now, I have problem with the 2nd array. It gives three 2x2 matrices for both rows, while it was "supposed" to give five 2x2 matrices in the first row and three 2x2 matrices ONLY in the second row. What cou

Dear all, to make our life easier, I give you the following dataset (just this vector) and code! It gives me two arrays of different dimensions: the first is a 2x2x1 array and the second is a 2x2x2 array (please, feel free to correct me on the way I define the arrays. This is the first time I am w

I am looking at your pdf file. it doesn't match your description. There are no missing values in the vectors x, y, t. Each vector has length 55 which is not a multiple of 4, so we don't know where the 2x2 matrices come from. The code doesn't run. There are are too many "}". PDF files are format
