Question

Please write the code using matlab

1) i. Create an anonymous function named optimist, that accepts a single variable as input i Create a row vector Tthat represents the number of seconds in two minutes, starting ii. Call the function optimist on the vector T, store the result in variable R1 and returns the double of that variable from one and ending at a hundred and twenty v. Create an anonymous function named pessimist, that accepts a single variable as input and returns the half of that variable Call the function pessimist on the vector R1, store the result in variable R2 Create an anonymous function named realist, that accepts a single variable as input and successively applies the functions optimist & pessimist, then returns the result. Hint Functions can be inputs to other functions v. vi. i i Call the function realist on the vector T, store the result in variable R3 Create an anonymous function named empiric, that accepts two variables as input. This function should return one if the input variables are equal, and zero otherwise. Hint: Incorporate a built-in function that determines if all values in a vector are greater than zero. For simplicity, you can assume that this function will only be called with inputs of equal dimensions ix. Call the function empiric on the vectors R2 and R3, store the result in R4 x. Create an anonymous function named nihilist, that accepts a single variable as input and returns zero xi Call the function nihilist on the vector R4, store the result in RS xii Print R5

Answer 1

i) Please save this code as optimist otherwise it will not work

function f=optimist(a)
f=a.*2;
end

ii)

T=linspace(1,120,120);

Output-

T =

iii)

T=linspace(1,120,120);
R1=optimist(T);

iv) please save this code with name pessimist otherwise it will not work.

function f=pessimist(a)
f=a./2;
end

v.)

R2=pessimist(R1);

--------------------------------------------------------------------------------------------------------------------------------------

Output-

R2 =
