%assuming you have this set of data in an excel file

%you can use the "xlsread" command in MATLAB and assign each collum to a variable

%lets say your file name is "filename"

%lets alos assume the first collumn contains the latitude data

%the second collumn contains the longitude data

%the third collumn contains the data on the height

%%Then here you go

latitude=xlsread('filename.xlsx','A1:A30');

longutide=xlsread('filename.xlsx','B1:B30');

height=xlsread('filename.xlsx','C1:C30');

save('MyData.mat', 'MyData')

[aixat amxan]

thanks sir. but, i cannot load them.

>> load(MyData.m)
Undefined variable "MyData" or function "MyData.m".

[Walter Roberson]

load('MyData.mat')

Notice the string must be quoted and notice it is .mat not .m

[aixat amxan]

sorry sir. how i can quote the string? i dont have basic for matlab. this i wanna to try to learn.

>> load('MyData.mat') Error using load Unable to read MAT-file C:\Users\Admin\Desktop\Semester 7\thesis\newUKC\try\MyData.mat: not a binary MAT-file. Try LOAD -ASCII to read as text.

[Walter Roberson]

That form of load is fine. What command did you use to save the data from MATLAB?

[aixat amxan]

i dont use any command. i only click save as at the save menu. then i save MyData.mat.

[Walter Roberson]

Use the save command shown

[aixat amxan]

sorry sir. i dont understand

[Walter Roberson]

Do not click on "save as" in the save menu. Instead give the command at the command line

save('MyData.mat', 'MyData')

[Azzi Abdelmalek]

You can save your data in a mat-file

v=[1 2 3;4 5 6] % Example
save filename v

To load them use load function

[aixat amxan]

thanks sir. i already try to create my data likes yours but cannot help me. sorry sir
