Hello,

I've got 3 signals of vibration that i load to the workspace by a acces file, Matrix of data 25602 x 3

X=rsplus(1:25602,1);
Y=rsplus(1:25602,2);
Z=rsplus(1:25602,3);

i'd like to calcul the RMS of each of these signal between two frequency F1=2Hz & F2=100Hz. 

I calculated the DSP of each signal by Welch Spectrum :

Hdsp_x=psd(h,X,'Fs',Fs)
Hdsp_Ypsd(h,Y'Fs',Fs)
Hdsp_Zpsd(h,Z'Fs',Fs)

Please, anyone can help me !!
