Create for loop to read in multiple excel files

Have this as my code so far:

%%Clear the workspace
clc;
clear all;
close all;

%%Import Data
imp = xlsread('HiG_67.csv','J:J');                                         %Import 'x ACC' Data
FilterValue=30;                                                            %Filter values less than 30
imp(imp<FilterValue)=0;                                                    %Set values less than 30 to 0

time= xlsread('HiG_67.csv','C:C')';                                        %Create time variable

%%Plot data and Calculate mean/SD
plot(time,imp)                                                             %Plot time against filtered data

n=sum(imp~=0);                                                             %Calculate mean of filtered data
n(n==0) = NaN;
m = sum(imp) ./ n;

sd=sqrt(sum(imp.^2)./sum(imp~=0) - m.^2);                                  %Calculate Standard Deviation

%%Output data into Excel file
filename = 'Filter_67.csv';
xlswrite(filename,imp);

Now I would like to create a loop to read in 28 .csv files from the same folder, they are all titled 'HiG_**.csv' ( being 67-94). If I could then filter them all then output them as 'Filter_**.csv'

Thanks

See the FAQ How can I process a sequence of files? I'll note I'm particularly fond of the dir solution for processing the input files in cases such as you've outlined.
