T maxElement ( const Array< T > &  v,

unsigned  start = 0,

) [inline]

Returns the maximum value stored in array "v" between the positions "start" and "end" - 1.

The positions of the values apply to the positions of the values in the element vector Array::e.
Besides returning the maximum value, the index (i.e. position in the element vector) of the maximum value is stored.

Parameters:
v the array of which the maximum value will be returned
ind index of the determined maximum value in the element vector
start the first position in the element vector where the method will search for the maximum value, the default value is "0"
end the first position in the element vector where the method will not search for the maximum value any more. If end is set to "0" (the default value), then the number of elements of the element vector is taken for end. end must be greater or equal than start, otherwise it will be set to the value of start
Returns:
the maximum value of v in the interval [start, end[
Exceptions:

The positions of the values apply to the positions of the values in the element vector Array::e.
Besides returning the minimum value, the index (i.e. position in the element vector) of the minimum value is stored.

Parameters:

Parameters:
i index of the subarray that will be returned
Returns:
constant reference to the subarray with index i
Exceptions:
SharkException if the type of the exception is "size mismatch", then the array has no dimensions. If the type is "range check error", then the value of i exceeds the size of the array's first dimension

Array< unsigned > Array< T >::pos2idx ( unsigned  p  )  [inline, inherited]

Given an absolute position "p" in the element vector Array::e, the positions relative to the single dimensions of the array are returned.

Parameters:
p the absolute position
Returns:
an array with the positions due to the single dimensions of the current Array object
Exceptions:
SharkException the type of the exception will be "range check error" and indicates that p exceeds the number of elements of the current array
Example
Guess you have an $5 \times 4$ array, i.e. an array with a total number of 20 elements. You want to extract the element at the absolute position 13 of the element vector (containing elements with indices 0 to 19).
Transformed to the array as seen by the user, you will get the relative positions $(3,1)$, because $3 \ast 4 + 1 = 13$.
