This code is automatically generated and works however, one could also use: all_data = ds.readall() įor each CSV file the importfile requires 48 seconds, the ds.readall only takes 0.2 seconds. Idx = (rawStringColumns(:, catIdx) = "") įLinsurancesample.policyID = cell2mat(rawNumericColumns(:, 1)) įLinsurancesample.statecode = categorical(rawStringColumns(:, 1)) įunty = categorical(rawStringColumns(:, 2)) įLinsurancesample.eq_site_limit = cell2mat(rawNumericColumns(:, 2)) įLinsurancesample.hu_site_limit = cell2mat(rawNumericColumns(:, 3)) įLinsurancesample.fl_site_limit = cell2mat(rawNumericColumns(:, 4)) į_site_limit = cell2mat(rawNumericColumns(:, 5)) įLinsurancesample.tiv_2011 = cell2mat(rawNumericColumns(:, 6)) įLinsurancesample.tiv_2012 = cell2mat(rawNumericColumns(:, 7)) įLinsurancesample.eq_site_deductible = cell2mat(rawNumericColumns(:, 8)) įLinsurancesample.hu_site_deductible = cell2mat(rawNumericColumns(:, 9)) įLinsurancesample.fl_site_deductible = cell2mat(rawNumericColumns(:, 10)) į_site_deductible = cell2mat(rawNumericColumns(:, 11)) įLinsurancesample.point_latitude = cell2mat(rawNumericColumns(:, 12)) įLinsurancesample.point_longitude = cell2mat(rawNumericColumns(:, 13)) įLinsurancesample.line = categorical(rawStringColumns(:, 3)) įnstruction = categorical(rawStringColumns(:, 4)) įLinsurancesample.point_granularity = cell2mat(rawNumericColumns(:, 14)) %% Make sure any text containing is properly converted to an categorical If nargin.*?)(?(*(\d+*)+ % Replace non-numeric cells % FLinsurancesample = importfile('FL_insurance_sample.csv', 2, 36635) % from rows STARTROW through ENDROW of text file FILENAME. % FLINSURANCESAMPLE = IMPORTFILE(FILENAME, STARTROW, ENDROW) Reads data % FLINSURANCESAMPLE = IMPORTFILE(FILENAME) Reads data from text file %IMPORTFILE Import numeric data from a text file as a matrix. Learn more about csv, image I am given 3 csv files (depth.csv,width.csv,length.csv) which all include tons of data in them how would I display an image out of the csv files. This will produce something like: function FLinsurancesample = importfile(filename, startRow, endRow) He may try the Import Wizard and generate a function that will use textscan. Or there is the person who attended MATLAB training. There is the person who comes from C and will use fscanf function data = my_parse_file_function(filename)įileFormat = '%d,%d,%C' % this is customized according to the data MATLAB has several ways of doing this and to the beginner it can be overwhelming the number of ways to do the same thing. This returns the data from all the text files in the variable all_data. The magic happens when one performs: all_data = ds.readall() For text files, properties for parsing the files are pre-populated, such as: FileEncoding, Delimiter and MultipleDelimitersAsOne. MATLAB creates a datastore associated to the given files. from Import WizardĪn alternative could be to leverage the datastore function that is available in MATLAB since R2014b: ds = datastore('*.csv') % use custom MATLAB import function, e.g. This leads to the following common MATLAB construct. This works as it returns a structure with a list of the text files. To tackle the first part of the question most MATLAB users will start with: listFiles = dir('*.csv') I really don't understand how to make an image out of this. The very large file contains depths where the rows correspond to the longitudes in the longitude file, and the columns correspond to the latitudes in the latitude file. This file has over 36 thousand rows and 18 different columns with different datatypes, all separated by commas. I'm trying to use 3 csv files (attached) to display an image.
