-------------------- table or array stuff -------------------------------
tab_abs			 calculates the absolute value of every sample within begin- and end-index
tab_add			 calculates the sum of every sample of 2 tables within begin- and end-index
tab_add_scalar		 calculates the sum of every sample with a scalar value within begin- and end-index
tab_carth2polar		 converts the samples of 2 tables read as carthesian coordinates within begin- and end-index
				into samples read as polar coordinates
