# padLinDim

Below is a demonstration of the features of the `padLinDim` function

## Contents

```
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;
