Can you please explain the meaning for below code ..??

function buildingDetection(inputFileName, outputFileName)

   [imgFile, lidarFile, demFile, LPDx, LPDy, useEntropy, useAdjustment,useRefinement, useReduction] = readInputFile(inputFileName);  

out = 'reading data ...';

[A, R, bbox] = geotiffread(imgFile);

[Ad, Rd, bboxd] = geotiffread(demFile);

fp = fopen(lidarFile, 'r');

ALS = fscanf(fp, '%f %f %f', [3 inf]);

fclose(fp);

ALS = ALS';
