I hope there will better answers. Share
WebJul 5, 2012 · The way you have defined you inline function, it is going to contain the variable o, rather than replacing it with the loop's value of o. I think what you want instead is this: Theme Copy f = inline ( ['min (x.+d (',num2str (o),',5),-x.+d (',num2str (o),',3))']) Also, o is a terrible name for a variable. ;-) 0 Comments Honglei Chen on 5 Jul 2012
