% Load coastline data from the shapefile
coastData = shaperead('your_coastline_file.shp');
% Extract relevant variables
meanValues = [coastData.mean];
stdDevValues = [coastData.stdDev];
% Analyze mean values
meanTrend = gradient(meanValues); % Calculate the rate of change of mean values
% Identify coastlines in erosion
erosionIndices = find(meanTrend < 0); % Find indices where mean values are decreasing
% Display results
fprintf('Coastlines in erosion:\n');
for i = 1:numel(erosionIndices)
index = erosionIndices(i);
fprintf('Coastline %d\n', index);
end
% Plot mean values and standard deviations for visualization
figure;
subplot(2, 1, 1);
plot(meanValues);
xlabel('Coastline Index');
ylabel('Mean Value');
title('Mean Values over Coastlines');
subplot(2, 1, 2);
plot(stdDevValues);
xlabel('Coastline Index');
ylabel('Standard Deviation');
title('Standard Deviation over Coastlines');
Please note that this is a general approach, and the specific interpretation of erosion may vary depending on the context and domain knowledge. You may need to fine-tune the criteria or incorporate additional factors based on your understanding of the coastal dynamics in the study area.
iska bhi code no error but data ni diya h question wale ne toh code me no error but we need relevant data ok
