function NumDiff()%We solve part A
'Part A'
%Setting the arbitrary values of step and original point
h=0.001;
x0=1;
%Calculating derivatives using the diff function that contains to values of
%input function and step as an input and outputs the approximate value of
%derivative
'Forward differentiation'
diff(h,inp(x0+h),inp(x0))
'Backward differentiation'
diff(h,inp(x0),inp(x0-h))
'Center differentiation'
diff(h,inp(x0+h/2),inp(x0-h/2))
'Part B'
%We create array of values%
startValue = 1;
endValue = 10;
nElements = 100;
stepSize = (endValue-startValue)/(nElements-1);
A = startValue:stepSize:endValue;...
