Too many input arguments ?

I have the following m script that is going to ask a function in anuther m script. For some reason fixplot is being given too many input arguments and I don't know why.

Her is the code for the main function that will be calling the other function.

function lab5

% lab5.m

% You will provide the print-out for the following

clear all;

clc;

% A (non-causal) bandstop filter

figure

fizplot([1 2 2], [0 1 .8]);

title('A (non-causal) bandstop filter');

/// And her is the function it is trying to call and place its input through.

function fizplot(b, a)

clf;

b = b(:)';

a = a(:)';

fplot(b, a, 'XLim', [0 1], 'XTick', 0.25);

h = get(gcf, 'Children');

for i = 1:2

set(h(i), 'Units', 'normalized');

pos = get(h(i), 'Position');

pos(3) = 0.33;

set(h(i), 'Position', pos);

end

subplot(2, 2, 2);

zplot(b, a);

title(['H(z)=' bastrnew({b, a}, 1)]);

subplot(2, 2, 4);

iplot(b, a);

figure(gcf);

return

/// And this is the error message i keep getting every time I run the code.

Error using fplot

Too many input arguments.

Error in fizplot (line 15)

fplot(b, a, 'XLim', [0 1], 'XTick', 0.25);

Error in Lab5 (line 8)

fizplot([1 2 2], [0 1 .8]);

Answer 1

[Basil C.]

The function fplot is used to plot functions. The input that you are providing are array elements so you could rather use

plot(b,a);

Also the function fplot does not take the limits of the functions (y=f(x)) as an argument, it can only take the limits to 'x'

Sorry my question was incomplete. "Fplot" is aouther function as well. It is posted bellow.

function fplot(b,a)

w = linspace(0,2,512);

F = fft(b,512)./(fft(a,512)+eps);

subplot(2,1,1)

plot(w,abs(F))

subplot(2,1,2)

plot(w,angle(F)/pi)

xlim([0,1])

You have

function fplot(b, a)

That accepts only two arguments

fplot(b, a, 'XLim', [0 1], 'XTick', 0.25);

Tries to call fplot with 6 arguments.
