Unrecognized function or variable 'PolyLines_Shape'

Hi!

I am running a code to make shapefiles in the matlab for fractures. I do have the variable "Polyline_shape" but I am still getting the error of 'unrecofnized variable'. As we get this error when we dont have the define variable in function to operate but I have the variable in upper lines of codes. Please see an attachment for your reference.

for k=1:length(C)

[PolyLines_Shape(k).Tile_ID] = i;

% [PolyLines_Shape(k).Ortho_ID] = PolyLines{i,2};

% [PolyLines_Shape(k).BoundingBox] = [R{PolyLines_Georeferenced_Rotated{i,2},1}.LongitudeLimits(1,1) ...

% R{PolyLines_Georeferenced_Rotated{i,2},1}.LatitudeLimits(1,1); ...

% R{PolyLines_Georeferenced_Rotated{i,2},1}.LongitudeLimits(1,2) ...

% R{PolyLines_Georeferenced_Rotated{i,2},1}.LatitudeLimits(1,2)];

[PolyLines_Shape(k).Geometry] = 'PolyLine';

[PolyLines_Shape(k).Polyline_ID] = k;

[PolyLines_Shape(k).Polyline_in_Ortho_ID] = z;

% if C is a cell array

%[PolyLines_Shape(k).X] = C{k-j+1,1}(:,1);

% if C is not a cell array

[PolyLines_Shape(k).X] = C{k,1}(:,1);

% if C is a cell array

%[PolyLines_Shape(k).Y] = C{k-j+1,1}(:,2);

%if C is not a cell array

[PolyLines_Shape(k).Y] = C{k,1}(:,2);

z=z+1;

end

j=length(PolyLines_Shape)+1;

shapewrite(PolyLines_Shape,strcat(outfolder,outfilename));

disp(i)

clearvars C PolyLines_Shape;

toc

end

%% Writing shapefile

tic

%shapewrite(PolyLines_Shape,'D:\PhD\Automatic_Detection\Core_Fractures\Shape_Files\xz769_Rotated_Simplified.shp');

shapewrite(PolyLines_Shape,"C:\Users\Omer\Documents\MATLAB\Automatic-Fracture-Detection-Code-1.0.0\Shape_Files");

toc

Hi Omer,

Unrecognized function or variable 'PolyLines_Shape' error is due to unavailability of the variable PolyLines_Shape in the Workspace. I suspect this is due to usage of below statement in your code

clearvars C  PolyLines_Shape;% Remove this statement before shapewrite function

Troubleshoot the issue further with the breakpoints. if the above step doesn't work .
