The specpeak function determines the spectral peak wavelength for any given spectral power distribution (SPD).
See also: speccentroid
Usage:
sp = speccentroid(lam,spec)
Where:
| Parameter | Description |
sp | Returns the spectral peak wavelength. |
lam | Specifies the wavelengths, vector or matrix. |
spec | Specifies the spectral power distribution(s), vector or matrix. |
Examples:
Determine spectral peak of the V(\lambda) curve:
lam = 380:780;
VL = ciespec(lam,'VL');
sp = specpeak(lam,VL)
% plotting the result
plot(lam,VL)
grid minor
hold on
plot([sp sp],[0 1],'k--')
xlabel('\lambda in nm')
ylabel('relative SPD')
hold off

Result:
sp = 555
Determine the spectral peaks of the α-opic functions:
lam = 380:780; spec = ciespec(lam,'aopic'); aopicpeak = specpeak(lam,spec)

Result:
aopicpeak = 448 541 569 507 490
