I want to write a function that takes 3 matrices and 2 strings as an argument. I successfully passed matrices as an argument but i could not do the same thing for strings. Is there anyone who knows how i can use strings as an argument and how should i pass strings on the line that i call the function? I want to use the function several times and i have different names for xlabel and ylabel so i want to use these names as an argument.
function [ ] = plotAmplitudeSpectrum( inp_signal, time_vector, Fsample, xlabel, ylabel )
% Fsample: sampling frequency
L = length(time_vector);
Y = fft(inp_signal);
P2 = abs(Y/L);
P1 = P2(1:L/2+1);
P1(2:end-1) = 2*P1(2:end-1);
f = Fsample*(0:(L/2))/L;
plot(f,P1,'LineWidth',2);
title('Sinyalin Genlik Spektrumu');
xlabel(xlabel);
ylabel(ylabel);
end

Hi,
The issue is with the input names. Change the input names with variable names other than MATLAB inbuilt functions, You can place input to be xlabelstr, ylabelstr and then use them in the function as such:
function [ ] = plotAmplitudeSpectrum( inp_signal, time_vector, Fsample, xlabelstr, ylabelstr )
%...
xlabel(xlabelstr)
ylabel(ylabelstr)
You could directly pass as such:
plotAmplitudeSpectrum( inp_signal, time_vector, Fsample, 'X Label', 'y label' )
% Or even
plotAmplitudeSpectrum( inp_signal, time_vector, Fsample, "X Label", "y label")
Hope this helps.
Regards,
Sriram
