Ideally, my calculation needs to preallocate an array, myArray, (of predetermined length) in which each element is an array of structs — an array which may grow in length during the course of the calculation. These arrays of structs must grow independently, so at the end of the calculation, the array of structs in myArray(1) may have a different length than myArray(2), etc.
The memory need not be contiguous, neither for myArray nor for the array of structs myArray(i).
Trying this
myArray(1:10) = { [ struct('index',int32(0), 'result',[]) ] };% ... later, when an element needs to grow:
myArray(1) = { myArray(1); [ struct('index', int32(0),'result',[]) ] };
fails on that last line with the message, "In an assignment A(:) = B, the number of elements in A and B must be the same."
