Hello Dears, Here i got the one error undefined function 'degree' . can anyone say the solve? how i can get solution?
function [residus, Stat, coefficients] = Calcul_Coef_NEW(SN, type, table_pression_kPa, P, T, degree)
degree = input('Enter the degree of the polynomial: ');
table_pression_psi = table_pression_kPa * 0.145038;
% Fit the polynomial curve based on the specified degree
fitting_type = ['poly', num2str(degree)];
a='poly32';
[FCT_COR,GOF,OUTPUT] = fit([T, P], table_pression_psi, fitting_type);
% Calculate the residuals
residuals = table_pression_psi - FCT_COR(T', P');
residuals2=OUTPUT.residuals;
% Calculate the maximum and average residuals
Res_max = max(abs(residuals));
Res_moy = mean(abs(residuals));
SYNTH_RES{1, 1} = 'SN Capteur';
SYNTH_RES{2, 3} = 'P';
SYNTH_RES{1, 4} = 'Résidu max';
SYNTH_RES{1, 5} = 'Résidu moy';
SYNTH_RES{1, 6} = 'R²';
SYNTH_RES{1, 7} = 'Erreur standard (psi)';
SYNTH_RES{2, 1} = SN;
SYNTH_RES{2, 4} = Res_max;
SYNTH_RES{2, 5} = Res_moy;
%SYNTH_RES{2, 6} = NaN;
%SYNTH_RES{2, 7} = NaN;
SYNTH_RES{2,6}=GOF.rsquare;
SYNTH_RES{2,7}=GOF.rmse;
% Write the coefficients
coefficients = coeffvalues(FCT_COR);
for m = 1:length(coefficients)
SYNTH_RES{m+4, 1} = ['a', num2str(m-1)];
SYNTH_RES{m+4, 2} = coefficients(m);
end
SYNTH_RES{length(coefficients)+6, 1} = 'Pression banc (psi)';
SYNTH_RES{length(coefficients)+6, 2} = 'Pression banc (kPa)';

SYNTH_RES{length(coefficients)+6, 7} = 'Pression corrigée (psi)';
SYNTH_RES{length(coefficients)+6, 8} = 'Pression corrigée (kPa)';
% Write the data (P reference, temperature, ratio, residuals, P0) in psi & kPa
for i = 1:length(table_pression_psi)

SYNTH_RES{length(coefficients)+6+i, 6} = OUTPUT.residuals(i)*6.894757;
SYNTH_RES{length(coefficients)+6+i, 7} = FCT_COR(T(i),P(i));
SYNTH_RES{length(coefficients)+6+i, 8} = FCT_COR(T(i),P(i))*6.894757;
%SYNTH_RES{length(coefficients)+6+i, 9} = residuals_p32(i);

end
xlswrite(fullfile('.\results\Poly', strcat('SN', SN, '_synthese.xlsx')), SYNTH_RES, type);

@Cris LaPierre, since (at that time) there was no activity on that post, and there was on this thread, I flagged that particular question.

hello
I corrected all the bugs I could find - find my suggestions in the attached zip file
now the last point I cannot fully test is the fitting itself as I don't have the CF toolbox, but the "degree" issue is solved
all the best
