padLinDim

Below is a demonstration of the features of the padLinDim function

Syntax
Description
Examples
Linearly padding a vector
Linearly padding a matrix

clear; close all; clc;

Syntax

[XP,indOriginal]=padLinDim(X,numPad,padDim);

Description

Pads an array X allong dimension padDim with numPad entries which are linearly extrapolated allong that direction.

Examples

Plot settings

fontSize=35;

Linearly padding a vector

Create example vector

t=linspace(0,2*pi,50);
y=10*sin(t);

Linearly pad vector

numPad=5; %Number of elements to pad
padDim=2; %Dimension/direction to pad in
[yp,indOriginal]=padLinDim(y,numPad,padDim);
[tp]=padLinDim(t,5,2);

cFigure; hold on;
hp1=plot(tp,yp,'k-','LineWidth',3);
hp2=plot(t,y,'g-','LineWidth',5);
legend([hp2 hp1],{'Original','Padded'});
set(gca,'FontSize',fontSize);
axis tight; axis square; box on; grid on;
drawnow;

Linearly padding a matrix

Create example matrix

Y=y(ones(1,25),:);

Linearly pad matrix

numPad=15; %Number of elements to pad
padDim=2; %Dimension/direction to pad in
[Yp,indOriginal]=padLinDim(Y,numPad,padDim);

cFigure; hold on;
hp1=surf(Yp);
set(hp1,'FaceColor','w');
set(gca,'FontSize',fontSize);
axisGeom; camlight headlight;
drawnow;
