Write a function called piecewise that has one input a numbe

Write a function called \"piecewise\" that has one input, a number x, and one output, number y, that uses a conditional statement that implements the following piecewise function. Y = x^2 when 0 > x > -1 y = squareroot (-x) when -1 >= x y = cos (x - 1) when x >= 0

Solution

Please create piecewise.m file in matlab and paste below code

% this is function defination

function y = piecewise(x)

if((x > -1) && (x < 0)) %condition 1

y = x * x;

end

if(x <= -1) %condition2

y = sqrt(-x);

end

if(x >= 0) %condition3

y = cos(x-1);

end

end

Now from command window call the function as

>> piecewise(1)

>> piecewise(-0.3)

You will get answers for all the values and conditions mentioned in question
