Summary

An LSQ-object takes a total space of:

9 + (administration)  
(n + p)(n + p + 1)/2 + (normal array)  
4m + (error calculations)  
m(m + p) + (known sides)  
(n + p + 1)/2 + (pivot area)  
(n + p)   (solution) 8 byte words (44)

where n is the number of unknowns (2n if complex); m the number of simultaneously to be solved equations; p the number of external constraint equations. In the non-linear case two LSQ-objects are used. In cases where the inverted normal array is calculated (known constraints) a temporary storage of n2 8-byte words is used.

The following calls are available:
