25 Feb 2014 Regression through least square(normal equations) Basic least square algorithm (Normal equations) for regression Author: Koteswar Rao Jerripothula

What's the advantage of this over the many other curve fitting functions on the file exchange?

15 Aug 2013 String comparison The function searches for a string inside a given target and returns 1 for found or 0 for not found. Author: Christian

This can be replaced with

~isempty(strfind(str, substr))

or for your example

>> ~isempty(strfind('Marc goes fishing', 'goes'))

ans =

1

strfind also works for cell arrays

>> strfind({'Marc goes fishing', 'banafdsafas'}, 'goes')

ans =

[6.0000e+000] []

so could be adapted for your other use cases. It will be much faster than your loopy code, which is also inefficient in other ways.

12 Jun 2013 Euclidean distance Calculate euclidean distance Author: wadzapi

John D'Errico's ipdm does this much better:

12 Jun 2013 Closest Finds the value in an array X closest to the scalar b. Author: Matt

John D'Errics's excellent ipdm http://www.mathworks.co.uk/matlabcentral/fileexchange/18937-ipdm-inter-point-distance-matrix is more advanced, and supports lots of distance metrics, use the 'nearestto' option to get similar results to your funtion.

20 May 2013 Euclidean Distance The Euclidean distance between points p and q is the length of the line segment connecting them. Author: Daniel Bromand

Does not improve on ipdm from the file exchange

24 Jan 2014 tightfig Remove excess margins from figures. Author: Richard Crozier grega

02 Oct 2013 tightfig Remove excess margins from figures. Author: Richard Crozier Shen, Mike

25 Aug 2013 samesize Determine if all inputs are the same size in all dimensions. Author: Richard Crozier Simon, Jan

Another hint: ISEQUAL replies a scalar TRUE or FALSE, so there is no need for ALL().

02 Jul 2013 Display Formatted Text Table of Data Display data, mixed numeric and strings with optional col and row headers and your choice of col sep Author: Richard Crozier Noah

It blows my mind that some kind of similar functionality is not already built in to Matlab. Thanks for putting this together!
