C = dlmread('Spektra_Spektrometer2_p.txt.','\t','A3..B652');
x1= C(:,1);
y1= C(:,2);
[fitresult,gof]= sinFit(x1,y1);
i am Missing this. How do I get those numbers that define the Sinusfit
spek2 = dlmread('Spektra_Spektrometer2_p.txt','\t','A3..B652');
x1 = spek2(:,1);
y1 = spek2(:,2);
[fitresult,gof]= sinFit(x1,y1);
phi = -348.3; %how do i get this??
yfit = -0.28*sin(0.016*x1+phi)+1.284; %how to i get this??

See if the approach in Curve fitting to a sinusoidal function will do what you want. It uses only core MATLAB functions, no toolboxes.
