Trying to copy a column from a array into a tall array

2 visualizzazioni (ultimi 30 giorni)
Trying to copy a column from a double array into a multi-dimensional tall array:
IrregularRawDataTallArray(:,1, targetColumn) = InputArray(1:InputArraySize(1), sourceColumn)
I've tried some differnet syntax but I get a error:
"In the assignment A(m,n,...) = B, B must be either a scalar value or a tall array. "
This is confusing as isn;t a scalar just a single value - and also I don't want the InputArray to be a Tall Array - does this mean I can't do a vector operation on a tall array?

Use tall() around the new data column:
T = tall(rand(10,2));
Starting parallel pool (parpool) using the 'Processes' profile ... Connected to the parallel pool (number of workers: 2).
t = rand(10,1);
T(:,2) = tall(t);

I tried that but now a error says "Incompatable tall array arguments. The tall arrays must be based on the same datastore." Is it because the tall array comes froma datastore that special rules apply for writing to it?
