MATLAB (Matrix Laboratory) er et omfattende matematikkprogram med eget scriptspråk basert på C. Cleve Moler, leder for computer science ved University of New Mexico, startet utviklingen av MATLAB på slutten av 1970-tallet.Moler ønsket å gi studentene tilgang til LINPACK og EISPACK uten å måtte lære seg Fortran.MATLAB ble raskt etterspurt av andre universiteter som også ønsket å. MATLAB, as mentioned by others, is great at matrix manipulation, and was originally built as an extension of the well-known BLAS and LAPACK libraries used for linear algebra. It interfaces well with other languages like Java, and is well favored by engineering and scientific companies for its well developed and documented libraries MATLAB is a programming language developed by MathWorks. It started out as a matrix programming language where linear algebra programming was simple. It can be run both under interactive sessions and as a batch job. This tutorial gives you aggressively a gentle introduction of MATLAB programming. MATLAB provides some special expressions for some mathematical symbols, like pi for π, Inf for ∞, i (and j) for √-1 etc. Nan stands for 'not a number'. Use of Semicolon (;) in MATLAB. Semicolon (;) indicates end of statement. However, if you want to suppress and hide the MATLAB output for an expression, add a semicolon after the expression MATLAB has powerful graphic tools and can produce nice pictures in both 2D and 3D.

A simple integer is considered an matrix of one row and one column
If you don't have MATLAB you can get a free evaluation, at least for academic purposes. You can also do many of the things MATLAB can do using open-source Octave (though there are significant limitations) I'm working on a homework assignment where I have to increase the pixel intensity of every 50th ro of an image by a factor of 10. I'm just confused on what intensity means/how to code for it: would I just say multiply the pixel value by 10 (and if so, how do I do that?) or do I say something like pixelintensity=pixelintensity*10 I mean how could we define or describes it? I am new to MATLAB. I have calculated the the Frequency of 1st zero, Level of 1st slobe, Level of 2nd slobe and level of 3rd slobe in Rectangular, Triangular, Hann, Hamming, Blackman etc type in Frequency Domain after typing wintool in the window command of the MATLAB

They'll learn how to work with variables, functions, and vectors MATLAB users should be aware that the tiny difference between pi as defined in MATLAB and the fundamental constant pi can lead to unexpected results in calculations. For example, the expression sin(pi), which one would expect to return 0, actually returns 1.2246e-16 in MATLAB
Looking for online definition of MATLAB or what MATLAB stands for? MATLAB is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms The Free Dictionar MATLAB will execute a file named 'startup.m' in the directory it was called from on the command line. Old versions of Octave do not. Starting with Octave 4.2.0 it behaves the same as Matlab. For older versions of Octave, it will execute a file named '.octaverc' which can be edited to execute existing startup files Before Matlab code can be executed, it must be compiled, which creates a binary instruction version of the Matlab commands. Normally this occurs automatically as needed, and happens so fast that you never notice it. It is possible to pre-compile Matlab m-files into p-files, using the pcode command
