Question

. Create a Matlab script that will load the file finc.mat and create a structure from the appropriate with the following fields: • Company (string) • First_Name (string) • Last_Name (string) • Address (string) • Credit_Card_Number (Integer) • Account_Balance (Real) • Credit_Score (Real) • Transaction (Array) To the right of the field names above are the data type in parentheses. Your code should calculate and display the following: • The descriptive statistics discussed in class of the Credit Scores for each customer. • The Credit Score that is the demarcation of the top 10% of credit scores. • The full name, company, address, account balance, and credit score of the individual with the lowest credit score

Answer 1

function [output]=dataconv(input,src_sig)
%
% dataconv
%
% Convolves the data stored in the input matrix with the selected source
% signature.
%
% IMPORTANT:
% PRELOAD DATA IN WORKSPACE
%
% Variable description:
% - input = input matrix, preloaded in workspace,  call without
%   hyphens nor .mat extension
% - src__sig = selected source signature, already resampled and centered, preloaded in workspace, call without
%   hyphens nor .mat. If .asc, there is no need to preload in workspace, replace 
%   src_filename=load('filename.asc'), i.e.: output=dataconv(data,load('filename.asc'))
% 
%
% EXAMPLE:
% test=dataconv(src6p,PGSsig1);;
