I am working on obstacle avoidance and path following code. For which I have made different functions in matlab. My question when ever I run them it says "Not enough input arguments".Is this is the problem with Matlab software ,I am using R2017a.

code for obstacle drawing

function drawObstacles(obstacles)
if(~ isempty(obstacles))
    plot(obstacles(:,1), obstacles(:,2), '.k'); %plot the obstacles
end

How are you invoking this code?

I don not understand your question Sir

[madhan ravi]

He is asking that how you call the function , can you show us how you are calling it?

[Walter Roberson]

For example, are you running this code by being in the editor displaying the code and pressing the green "Run" button?

[passioncoding]

Green button

[madhan ravi]

You should not run a function file . Read the link below:

I you use the green run button, the default is to run the function without any inputs. So you should either use the dropdown under the run button to insert your variable, or you should write the code in a script or in the command windown.
