Robotics toolbox Custom map compile error
显示 更早的评论
Hey there,
I am using MATLAB 2018a and i have robotics toolbox installed.
I am using it for path planning, the "exampleMaps.mat" map that is already there works just fine but when I make a custom maps it doesn't work.
It shows compile error:
""Undefined function or variable 'simpleMap'.
Error in Untitled12 (line 4)
map = robotics.OccupancyGrid(simpleMap,2);""
this error doesn't come when when i use "exampleMaps.mat"
this is my code
function b=map()
filePath = fullfile(fileparts(which('PathPlanningExample')),'data','exampleMaps.mat');
load(filePath)
map = robotics.OccupancyGrid(simpleMap,2);
prmSimple = robotics.PRM(map,50);
s=[2 2];
e=[10 2];
path=findpath(prmSimple,s,e)
show(prmSimple)
end
For your information let me tell you that my map is in same directory as "exampleMaps.mat"

Hello Divyanshu,
Does your MAT file have a variable in it called "simpleMap"? Because that is what the code is looking for - a variable called simpleMap that has been loaded into the function workspace. If your MAT file uses a different variable name for the map data, simply change "simpleMap" to reference that instead.
As an aside, I prefer to use the load('myMatFile.mat', varName1, varName2) syntax when calling load. That makes it obvious where the variables are coming from.
