Arrays - Introduction

What are arrays?

When are they used/useful?

Many examples

- What?
- ONE variable that contains MORE THAN ONE value.

VECTORS (1D)

MATRICES (2D,3D..)

pressures

velocity

densities

temperatures

- Data Base (Keep data together)

Database

“VECTORS”

Keep the top 5 scores:

Keep the part numbers of a specific Gas Engine:

- Keep data together (data base)
- Create data tables (financial analysis…)

Data Tables

“MATRIX”

Financial: Loan Analysis

- Keep data together (data base)
- Create data tables (multiplication, sine, cosine, financial analysis…)
- Study properties of fluids (CFD)

Shock Waves

Aerodynamics

CFD = Computational Fluid Dynamics

->Solve and analyze problems that involve fluid flows

Shock Waves

Shock Waves

Aerodynamics

Matrices: Grids or Mesh

T : temperature

P : pressure

u : velocity

: density

Fluid Flow

Shock Waves

Aerodynamics

Matrices: Grids or Mesh

1st layer : T

2nd layer: P

3rd layer:

4th layer: u

Fluid Flow

Or.. 1 unique 3Dimensional array !!!

- Keep data together (data base)
- Create data tables (multiplication, sine, cosine, financial analysis…)
- Study properties of fluids (CFD)
- Upload tremendous amount of data from files

Files

- Online Data Files can be downloaded & Analyzed

- Keep data together (data base)
- Create data tables (multiplication, sine, cosine, financial analysis…)
- Study properties of fluids (CFD)
- Upload tremendous amount of data from files
Etc…

- What is an array?
- Difference between “vector” and “matrix”
- Various examples showing the big pictures of arrays
- What’s next? Creating arrays using MATLAB!
