Improved values as soon as they are computed, this does not ensure that the The current iteration), as well as variable values that have already beenĮven though the Gauss-Seidel’s method uses the Values from the previous iteration (whose values have not yet been evaluated in However in the Gauss-Seidel method, the “known” values are a mix of variable Thus in the Jacobi method, during the computations forĪ particular iteration, the “known” values are all from the previous iteration. Updated variables are used in the computations as soon as they are updated. On the other hand in the Gauss-Seidel method, the The computations only after all the variables (i.e. In the Jacobi method the updated vector x is used for Methods for solving the linear system Ax = b.

Values of unknowns of a system of linear equations. Reduced to reduced Echelon form using elementary row operations to obtain

In Gauss-Jordan method, the augmented matrix is.

Substitution is applied to get values of unknowns, occurring in a system of Matrix is reduced to Echelon form using row operations and then back

In Gauss- elimination method, the augmented.

These fluorescence and binding characteristics of the N-ethyl-substituted diamidine 1 are applicable for the detection of carboxylic acids in a protic solvent.Comparison between Gauss Elimination method and Gauss Jordan method The interesting tight binding of the diamidine 1 with α, ω-dicarboxylic acids was observed in 2-propanol- d 8 using 1H NMR and the restriction of the rotation of the phenyl rings of the 1,8- diphenylnaphthalene unit was also observed. Interestingly, the diamidine 1 does not emit in 2-propanaol before recognizing the α, ω-dicarboxylic acids, and succeeded in the detection of a dicarboxylic acid (turn-on response) in the protic solvent, 2-propanol.

However, at a low concentration (25 μM), the turn-on fluorescence detection of the dicarboxylic acids was not successful because the diamidine 1 emits in MeOH before recognizing the carboxylic acids. The diamidine 1 forms 1:1 complexes with the α, ω-dicarboxylic acids in the competing protic solvent, MeOH, using the charge-assisted hydrogen bonding (i.e., formation of amidinium-carboxylate), and the formation of the complexes was determined by 1H NMR and DOSY NMR spectroscopies in a high concentration (2.0 mM). A new diphenylnaphthalene-based diamidine ( 1) having an N-ethyl-substituent to improve its solubility has been designed and synthesized for the recognition of dicarboxylic acids.
