The array itself is also a kind of variable - an array variable. You need to be careful with arithmetic operations (addition, subtraction, multiplication, division, exponentiaion) when it comes to arrays - these things can be defined, but they have to be defined correctly. We'll look at this later. In MATLAB, surface is defined by the Z-coordinates of points above a grid in the x-y plane. Surface plot data describes the properties that control the color in this presentation Each of the elements of an array is a variable on its own, which can be used in a mathematical operation. E.g.:

Another option for matrix manipulation is that you can multiply the corresponding elements of two matrices using the .* operator (the matrices must be the same size to do this). The Matlab package also contains commands that translate MATLAB® code into Maple. Communication is initiated by Maple to evaluate commands in MATLAB® and possibly return a result

### Delete an Element from a Vector

Getting started. The most effective way for you to go through this tutorial is to run the listed example code in a MATLAB session as you proceed through the tutorial Manipulating vectors is almost as easy as creating them. First, suppose you would like to add 2 to each of the elements in the vector a. The equation for that looks like: For the general case where your matrix could be anything, you would want to create a symbolic representation of your matrix, compute the determinant, and solve for the variable of interest. You can do this using, respectively, the functions SYM, DET, and SOLVE from the Symbolic Math Toolbox:

While the elements of the array can be any kind of number, their positions are identified by integers: there is a first, a second, a third, a fourth, etc. up until the end of the array. It's standard to indicate the position of the array using bracket notation: in the above example, the first element ismakes perfect sense. In algebra, this would imply that 0 = 1, which is of course nonsense. In MATLAB, it means "take the value that a has, add one to it, then assign that value to a". This changes the value of a, but that's allowed. For example, type:If you want MATLAB to just assign the value of a calculation to a variable without telling you the answer right away, all you have to do is put a semicolon after the calculation:

and you need to solve for the values of omega that satisfy the condition det M = 0. How do you do this in MATLAB? It is surely something simple, but I haven't found the function yet Note how we put the labels on the axes - using the commands xlabel and ylabel, with the arguments 'x' and 'y'. Because the arguments are character strings - not numbers - they need to be in single quotes. The axis labels can be more complicated, e.g.A 的行列式相当大，尽管 A 是奇异的。实际上，A 的行列式应正好为零！由于 MATLAB® 实现的 LU 分解（det 用它来计算行列式）中汇总了舍入误差，因此 d 不精确。此结果演示计算数值行列式的一些重要方面。有关详细信息，请参阅局限性部分。Let's say you want to create a vector with elements between 0 and 20 evenly spaced in increments of two (this method is frequently used to create a time vector): and what we get is a plot of the array a versus the array b - in this case, a discrete version of the exponential function exp(x) over the range x=1 to x=5.

• In general, it's good to use brackets - they invovle more typing, and may make a computation look more cumbersome, but they help reduce ambiguity regarding what you want the computation to do.
• Dividing two polynomials is just as easy. The deconv function will return the remainder as well as the result. Let's divide z by y and see if we get x.
• There are also different ways to create the initial matrix A. Above, I did it with one string expression. However, I could instead use SYMS to define w as a symbolic variable, then construct a matrix as you normally would in MATLAB:
