Question

I want to plot a function y=1-exp(c) ,where as the range of x is defined. The plot is to be between x and the function y. The plot just shows just 1 point instead of showing a series of points exponentially.I am new in Matlab.Sp,please help me where I am going wrong Here is the code:

   for x = -10:0.25:10

   if(x>0)

   c=-6*x;
   m=exp(c);
   y = 1-m  

   end
   plot(x,y,'o')
   xlabel('x') 
   ylabel('y') 
   title('Plot')
   end

Answer 1

This should do it:

x = -10:0.25:10; % define the x vector
c=  -5*x.*(x>0); % using a  logical condition the 'if' is avoided
y = 1-exp(c);    % calc y given c

plot(x,y,'o')
xlabel('x') 
ylabel('y') 
title('Plot')

no ‘for’ loop or ‘if’ needed…
