i wanted to use power regression for values of vibrating mass equation:
the values are:
m=[0.0200 0.5000 0.1000 0.1500 0.2000 0.2500 0.3000 0.3500 0.4000]
T=[0.2000 0.3100 0.4600 0.5300 0.6200 0.7100 0.7600 0.8400 0.9100]
but i can't figure out that right function for power regression, would apprecaite some help

Hi Shatha,
First of all you need to fix the second value of m, which should be .0500 not .5000.
If T is proportional to sqrt(m), then T^2 is proportional to m. So
plot(m,T.^2,'-o')
shows a nice straight line (almost) which you can fit with linear regression.
