Problem $44948.$ Calculate a Damped Sinusoid The equation of a damped sinusoid can be written as

y $=$ A$.^(-$t$)*$cos$(2$ft$)$

where$$A$,$$,$ and$$f$$are scalars and$$t$$is a vector.

Calculate the output sinusoid$$y$$given the inputs below:

lambda $-$

T$-$ maximum value of$$t

N$-$ number of elements in$$t

Assume$$A $=1$and$$f $=1.$ The vector$$t$$should be linearly spaced from $0$ to$$T$,$ with$$N$$elements$.$
