Error using input, cannot call INPUT from EVALC

Hi, I was trying to write a function that calculate some statistic thing Here is my code

xmin = input('Input the min value for x: ');
xmax = input('Input the max value for x: ');
xspace = input('Input the increment for x: ');

x = xmin:xspace:xmax;

equation = input('Input the equation: ','s');
f = eval(equation);

F(xmin) = f(xmin);

for j = xmin +1 : xspace: xmax,
    F(j) = f(j) + F(j-1);
end

ymax = max([max(f), max(F)]);
ymin = min([min(f), min(f)]);

subplot (2,1,1); p = plot(x, f,'k'); set(p,'LineWidth',2); %k means black
xlabel('x'); ylabel('f(x)'); title('Probability Density Fuction');
axis([xmin,xmax,ymin,ymax]); grid;

subplot (2,1,2); p = plot(x, F,'k'); set(p,'LineWidth',2); %k means black
xlabel('x'); ylabel('F(x)'); title('Cumulative Distribution Fuction');
axis([xmin,xmax,ymin,ymax]); grid;

When I try to run this code, I don't have any problem, however when I try to publish the same code using matlab cloud I got some errors

Error using input Cannot call INPUT from EVALC.

Error in cdfpdf (line 1) xmin = input('Input the min value for x: ');

Also I can't run this code in matlab cloud, gave me a bunch of errors, I don't understand what these errors mean. Any help would be appreciated. Thanks in advance.

Huh. Sure enough, evalc('input()') is not allowed.

How can we help you with the bunch of errors, when we do not see the corresponding messages?
