Update: Please see this doc page: https://www.mathworks.com/help/map/working-in-utm-without-a-map-axes.html

************************************

Matlab has his own functions to deal with it.

First you need to get the utm zone from the coordinates

p1 = [lat,lon];
z1 = utmzone(p1)

Then you must get the geoid of this zone and construct the projection structcture using the following functions

[ellipsoid,estr] = utmgeoid(z1);
utmstruct = defaultm('utm');
utmstruct.zone = z1;
utmstruct.geoid = ellipsoid;
utmstruct = defaultm(utmstruct);

Finally you use mfwdtran to convert coordinates

[x,y] = mfwdtran(utmstruct,lat,lon)

Hello .

I have a problem with this code in zone part. I know that my lat and lon data is located in 40 zone of north hemisphere. But this code is showing me z1= 40S. what's the matter?

The above codes do not work when I use lat=29 and lon=-126

Load the data into matlab and use the following function to convert degrees to utm.

YOu can load data from excel to matlab using xlsread.

close all clear all workspace

%% ext='.xlsx'; filename1='João Carlos.xlsx'

%% Leitura Ficheiros

data_MOM1=xlsread(filename1,'MOMENTO1');

datautm_MOM1= wgs2utm(data_MOM1)

What's wrong in the code?

"Error using wgs2utm (line 68) Wrong number of input arguments

Error in newroutine (line 10) datautm_MOM1= wgs2utm(data_MOM1)"

在 MATLAB Online 中打开

    Lat = data_MOM(:,1) ;   % is X latitude? check 
    Lon = data_MOM(:,2) ;    % is Y longitude? Check
    [x,y,utmzone]= wgs2utm(Lat,Lon) ;
