why will my function not run in the main code

##This is the main code##

%% Problem IV %%
% ON SEPARATE M FILE
ellipsoid_volume(8,17,"Volume versus depth for an ellipsoid")

## This is the function code##

% This program calls the following user-written functions
% 1. ellipsoid_volume   
% Problem 1 - Calculate volume of ellipsoid shaped tank.
figure(1)
ellipsoid_volume(3,12,'Volume versus depth for an ellipsoid')
function ellipsoid_volume(a,b,plot_title,units)
%volume of horizontal ellipsoid
%inputs:
%a - vertical semi-axis
%b - horizontal radius
%plot_title - string holding plot title
%units - optional string describing units, default = 'm'

if(nargin==3)
units='m';
end

h=linspace(0,a);

V=pi/3*(3*a-h).*(b*h/a).^2

plot(h,V)
grid on

title(plot_title);

xlabel(['Height(',units,')']);
ylabel(['Volume(',units,'^3)']);
end

Please help. See error attached.

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

Brother the error is basically due to the fact your function file name ellipsoid_volume.m does not contain only function. So,

Firstly copy only the below bold part to file name ellipsoid_volume.m and then run the separate file function. Also, alternatively you can copy whole below code in a script and run it. It will run.

clc
clear all
close all
figure(1)
ellipsoid_volume(3,12,'Volume versus depth for an ellipsoid')
function ellipsoid_volume(a,b,plot_title,units)
%volume of horizontal ellipsoid
%inputs:
%a - vertical semi-axis
%b - horizontal radius
%plot_title - string holding plot title
%units - optional string describing units, default = 'm'

if(nargin==3)
units='m';
end

h=linspace(0,a);

V=pi/3*(3*a-h).*(b*h/a).^2;

plot(h,V)
grid on

title(plot_title);

xlabel(['Height(',units,')']);
ylabel(['Volume(',units,'^3)']);
end
