Hello, for whatever reason, writematrix is not working for me in MatLab. I need to write my results into an excel file and I don't know what else to do. No matter what I do, I cant fix it.
Error:
Error using writematrix (line 206)
Execution of script mpower as a function is not supported:
E:\Program Files\MATLAB\R2021a\toolbox\matlab\ops\mpower.m
Error in Meh (line 27)
writematrix('Departure City:','table1.xlsx','Sheet',2,'Range','A6')
My Code:
close all
clear
clc
%load the table to read cities and their distances
table=[0 2 3 4
2 0 0 1
3 0 0 5
4 1 5 0]
table = xlsread('table1.xlsx');
L=length(table);
disp(['Cities and their distances: '])
table
disp(['Cities to choose from: 1 to ',num2str(L)])
prompt='Departure City:';
DepartureCity=input(prompt);
while (DepartureCity>L)
disp(['Sorry that this is NOT a city we know. Please enter a valid city number'])
prompt='Departure City:';
DepartureCity=input(prompt);
end
writematrix('Departure City:','table1.xlsx','Sheet',2,'Range','A6')

Your first input to writematrix needs to be a variable name, not a char. Change this:
writematrix('Departure City:','table1.xlsx','Sheet',2,'Range','A6')
to this
writematrix(DepartureCity,'table1.xlsx','Sheet',2,'Range','A6')

You do not specify a path, so MATLAB is trying to save the file in the current folder. Use the current folder browser to change this location.
Perhaps your virtual desktop cannot write to OneDrive. Run a test. In your virtual desktop (but not in MATLAB), can you create a file in the specified location?

The error reffers to mpower.m being a script and not a function. mpower is a builtin function, and mpower.m contains only help text. It seems that MATLAB isn't detecting the builtin function, which is likely an installation issue. you can try reinstalling from scratch, that should resolve the issue.
