WARNING !! Matrix are stored column ways. Ex : double M[4] = {1.0, 2.0, 3.0, 4.0, 5.0, 6.0} - If M has 2 lines and 3 columns : M = [ 1.0 3.0 5.0 ] [ 2.0 4.0 6.0 ] - If M has 3 lines and 2 columns : M = [ 1.0 4.0 ] [ 2.0 5.0 ] [ 3.0 6.0 ] I.1 - Real I.1.1 - Simple precision (float) I.1.2 - Double precision (double) I.2 - Complex I.2.1 - Simple precision (float) I.2.2 - Double precision (double) I.3 - Integer (NOT IMPLEMENTED YET) I.4 - Boolean (NOT IMPLEMENTED YET) /* ** Functions Naming style */ We define this coding style for functions names : <precision><function_name><variable_type>. variable_type : - 's' : Scalar - 'a' : Matrix precision : - 's' : Real simple precision (float) - 'd' : Real double precision (double) - 'c' : Complex simple precision (float) - 'z' : Complex double precision (double) /* ** Transtyping functions ** FIXME : Add it into the users limitations. */ - acos(x) : Real input. Return a Real value if x E [ -1 ; 1 ]. Return a Complex value if x E ] -inf ; -1 [ U ] 1 ; +inf [. - acosh(x) : Real input. Return a Real value if x E ] 1 ; +inf [. Return a Complex value if x E ] -inf ; 1 ]. - asin(x) : Real input. Return a Real value if x E [ -1 ; 1 ]. Return a Complex value if x E ] -inf ; -1 [ U ] 1 ; +inf [. - atanh(x) : Real input. Return a Real value if x E ] -1 ; 1[. Return a Complex value if x E ] -inf ; -1 [ U ] 1 ; +inf [. - log(x) : Real input. Return a Real value if x E ] 0 ; +inf [ Return a Complex value if x E ] -inf ; 0 [ - log10(x) : Real input. Return a Real value if x E ] 0 ; +inf [ Return a Complex value if x E ] -inf ; 0 [ - spec(A) : Real input. Return a Real value if A symmetric and for some other cases (to complete) Return a Complex value otherelse - spec2(A) : Real input. Return Reals value if A symmetric and for some other cases (to complete) Return Complexes value otherelse - logm(A) : Real input. Return either a Real value or a Complex value : don't know the conditions to have one - powm(A) : Real input. Return either a Real value or a Complex value : don't know the conditions to have one - chol(A) : Complex input The diagonal must be real; -max(a,b) : Real input only -min(a,b) : Real input only Following fuctions must have their 2 input matrix with the same dimension(row1=row2 and column1=column2) -operation element by element : add, diff, rdiv, ldiv, mul -comparaison operators : LogEq, LogNe, LogGt, LogGe, LogLt, LogLe -pow Following fuctions must have a square matrix on input -logm -powm -determ -chol -trace -lpc2cep (because using logm) -spec -spec2 -inv -Careful about the functions ceil, floor, fix/int, round with float precision. Exemple : floor(1,999999)=2 instead of 1 in Scilab floor(1.99999)=1 egal to Scilab result
