![]() ![]() On the PC, adding & to the end of the ! command line, as in !dir &, causes the output to appear in a separate window. Indicates that the rest of the input line is issued as a command to the operating system. ![]() MATLAB displays the first contiguous comment lines in a M-file in response to a help command.Įxclamation point. The percent symbol denotes a comment it indicates a logical end of line. Used after an expression or statement to suppress printing or to separate statements. For multi-statement lines, the comma can be replaced by a semicolon to suppress printing. Used to separate statements in multistatement lines. Used to separate matrix subscripts and function arguments. Three or more points at the end of a line indicate continuation.Ĭomma. A.(field) and A(i).field, when A is a structure, access the contents of field.Ĭontinuation. See the Arithmetic Operators page.įield access. 314e1 are all the same.Įlement-by-element operations. A quotation mark within the text is indicated by two quotation marks.ĭecimal point. 'any text' is a vector whose components are t he ASCII codes for the characters. X' is the complex conjugate transpose of X. For example, A(,:) = A(,:) interchanges rows 1 and 5 of A. If V has m components and W has n components, then A(V,W) is the m-by- n matrix formed from the elements of A whose subscripts are the elements of V and W. The same indirect subscripting works in matrices. If X has n components, X(n:- 1:1) reverses them. See help paren for more information about ( ). An error occurs if any such subscript is less than 1 or greater than the size of X. The components of V must be integers to be used as subscripts. To add comments to MATLAB code, use the percent ( ) symbol. They are also used to enclose subscripts of vectors and matrices in a manner somewhat more general than usual. While commenting a block of code can be done by adding a symbol at the beginning of each. They are used to enclose arguments of functions in the usual way. Parentheses are used to indicate precedence in arithmetic expressions in the usual way. It may come back, and it is a useful language to know, but if you ever want a job then it wouldn't be my first language.Special Characters ( ). You can mark selected text in the MATLAB comments so that they display in italic, bold, or monospaced text when you publish the file. There was some thought at one point that it would replace python, but instead python popularity has been skyrocketing and Julia popularity plummeting. The problem is that it is just not widely used compared to MATLAB and Python. Julia is an interesting language for some of the same problems MATLAB intends to solve, and has a very passionate following. So an experienced python programmer writing MATLAB code will most likely write better MATLAB code than an experienced MATLAB programmer. MATLAB, in contrast, discourages many of them. It is easier to switch from python to MATLAB than the other way around, and much easier to switch from python to another language than to switch from MATLAB to another language.įurther, python is explicitly designed to encourage you to follow safe, effective programming practices. More importantly, though, because of the strange way MATLAB works it is relatively hard to move to another language if you only know MATLAB. In particular MATLAB makes it easy to fall into a trap where you think you know what it is doing, but it is actually doing something completely different and this ends up biting you in the ass eventually. MATLAB is slightly easier to get started on for a narrow range of problems, but has a wide variety of idiosyncracies and corner cases that make it harder to understand completely. So my question is to know is it possible to use greek letters as variables? It's not a big problem if we can't use greek letters. This is just for better understanding and visualisation of the equation I implement in MATLAB. I suppose MATLAB doesn't recognize greek letters as variables. Check for unsupported symbol, invisible character, or pasting of non-ASCII characters. I tried to type : α=2īut MATLAB says Error: Invalid text character. I want that MATLAB creates the variable α in the Workspace. I've seen some of my teachers write : alpha=2 I know that it will write α and not alpha. I don't want to do that : title('Estimation of the value of \alpha') Let's take the letter alpha ( α ) so it will be clear. I'm not talking about displaying a greek letter. ![]() I have a very quick question as the title says. (If I am wrong, feel free to redirect me to a link/tutorial that solves my problem) I didn't find something similar on the internet and r/matlab so I ask it here. ![]()
