A(, 2:3)
A(;, [2,31)
A[2:3,]
A(;, 2-3)
Which of the following statements on scripts and MATLAB functions are true?
functions must have input or output variables

scripts use the command window's workspace
functions can be called within another function, whereas scripts cannot
Create a function called myButterfly which accepts an array of numbers (t) as
input. The corresponding array of X and Y coordinates should be the output. as
described by the following equations:
x = sin(t) e)-2cos(4t)-sin
y = cos(t) e – 2cos(4t)-sin
