## MATLAB: How to suppress the output of another function that is called from the function

bisectfunctionsubfunctionsupressurgent

I am trying to compile the roots calculated from a bisection method function and an incremental search method function. The output of nb from the incremental search function continually appears even when I suppress the incremental search function.

`%my original function`

function [X] = manyRoots(func,a,b,ns,tol)%manyRoots: root location zeroes

%combines bisect and incsearch to detect roots when sign change occurs

%input:

%func = name of function

%xl = lower bound of the bracket

%xu = upper bound of the bracket

%ns = number of sub intervals

%tol = the desired tolerance

%output:

%roots = real roots

y = bisect(func,a,b,tol);z = incsearch(func,a,b,ns);[X]=[y,z];end

I am trying to supress the nb from this function.

`function xb = incsearch(func,xmin,xmax,ns)% incsearch: incremental search root locator`

% xb = incsearch(func,xmin,xmax,ns):

% finds brackets of x that contain sign changes

% of a function on an interval

% input:

% func = name of function

% xmin, xmax = endpoints of interval

% ns = number of subintervals (default = 50)

% output:

% xb(k,1) is the lower bound of the kth sign change

% xb(k,2) is the upper bound of the kth sign change

% If no brackets found, xb = [].

if nargin < 3, error('at least 3 arguments required'), endif nargin < 4, ns = 50; end %if ns blank set to 50

% Incremental search

x = linspace(xmin,xmax,ns);f = func(x);nb = 0; xb = []; %xb is null unless sign change detected

for k = 1:length(x)-1 if sign(f(k)) ~= sign(f(k+1)) %check for sign change

nb = nb + 1; xb(nb,1) = x(k); xb(nb,2) = x(k+1); endendif isempty(xb) %display that no brackets were found

disp('no brackets found') disp('check interval or increase ns')else disp('number of brackets:') %display number of brackets

disp(nb)end

I am trying to suppress the number of brackets that shows up above my answer X.
