I need to create a matrix of integers (or floats) which I'd like to define as 2-dimensional array. How can I declare it in Qlarity ?

I tried it like

Code:
dim arr[3][3] as integer  ' or as float


but the compiler didn't liked in :-(

In the documentation, there's nothing mentioned about more-dimensional arrays.

How can I go on ?

Tony :-)

Unfortunately, Qlarity does not support multi-dimensional arrays. It is high on the list of features I would like to implement, however it is an extremely invasive change which is why we haven't done it yet.

For a rectangular matrix, the simplest solution is usually to use a single dimensional array and manually calculate the index. Such as

Code:
dim arr[9] as integer
dim x, y, idx as integer
dim value as integer
x := 1
y := 2
idx := 3*y + x
value = arr[idx]


For more complicated scenarios (jagged arrays, arrays of strings etc), there are some other Qlarity options that are more useful. This includes: "String Arrays" (in quotes because it is simulated) and the AllocateArrayHandle family of functions to reduce an array to a scalar value for storage into a linear array.
