Accessing multi dimensional cell array

[Rick T]

Greetings All

I have a cell array created like this how do I access the value
p000001 I tried m_ca2{2,1,3} but it comes back as an error

m_ca={'Resonance
Freq','number','Filename','time','fs','Split-3675','Session Num'}
m_ca2={277.912902832031250,1,'p000001','00:00:01',44100,3675,0}
m_ca2={m_ca;m_ca2}

Thanks
