plot matrix with variables

Hello , i am trying to plot the following matrix :

Y= [ sin(2*pi*t) sin(2*pi*t) sin(2*pi*t) ]

[ sin(2*pi*t) sin(2*pi*t) sin(2*pi*t) ]

[ sin(2*pi*t) sin(2*pi*t) sin(2*pi*t) ]

for a given value of t , i ve used plot function but i ve got this error :

(Data must be numeric, datetime, duration or an array convertible to double.)

Appreciate your support .

N = 100 ; 
t = linspace(0,2*pi,N) ; 
y = sin(2*pi*t) 
plot(t,y)
