#TYPING A COMMENT IN MATLAB SERIES#

Matrix Right Division (/)įor instance, when B and A are two matrices, B/A and B*inv(A) are nearly equivalent. So, given that A and B are the same size, C= A.*B. This operator performs the function of multiplying element of each operand with the other. The condition for this to occur is if the number of columns in A is equal to the number of columns in B and if both the operands are non-scalar. Matrix MultiplicationĬ is considered the linear algebraic product of A and B if C= A*B. In this case, both values have to be the same size. Subtraction Operator (-)Īs the name suggests, this operator performs the function of subtracting one value from the other. If not, one of them has to be a scalar value. The condition for adding two values is that both the values have to be the same size. Addition Operator (+)Īs the name suggests, this operator performs the function of adding two values. What differentiates the array arithmetic operator from the matrix arithmetic operator is that in the case of the array arithmetic operator, we will use a (.). If we use the Arithmetic operator with one or more operands as a matrix, it is called a matrix arithmetic operator. If the Arithmetic operator is used with one or more operands as arrays, then it is called Array arithmetic operators.

There are two types of Arithmetic operators in Matlab. There are different types of Matlab operators.

Matlab operates on whole arrays and matrices hence, Matlab functions work on non-scalar and scalar data. Matlab deals with different variables, functions, and arithmetic operations using several operators, symbols, and special characters. These symbols in common are called operators. For example, the - sign refers to the operation subtraction, while the symbol + refers to the operation of addition. It can also be defined as a character that represents an action. In the next part, we’ll discuss a few more enhancements to this feature.In computer programming and mathematics, the term operator refers to a symbol used to perform specific logical and mathematical operations. In R2010b, comment wrapping abides by this simple rule: if there’s no whitespace, don’t break! This means that URLs, or any long strings, are preserved: That’s no good for reading and was particularly pernicious for publishing: This was true with automatic comment wrapping as well – if you were typing a long string and reached the right-hand margin, it would break. One frustrating behavior of comment wrapping prior to R2010b was that if your comments contained text that shouldn’t be broken, such as a URL in publishing hyperlink markup, comment wrapping would go ahead and break it: This allows independent “paragraphs” of comments to remain intact and prevents them from being strung together, even if you do a “Select All” > “Wrap Comments” to reformat your whole file. So a non-comment line, a blank line, or a comment indented differently each represents the end of a section.

So what defines a section? Hopefully, exactly what you’d think: a series of contiguous, identically-indented comment lines.

Note that the Editor wraps only the current “section” of comments. This allows you to tidy up what you’ve written without taking you out of the flow of typing. Your caret could in fact be anywhere on lines one through five.

Now you can simply press Ctrl-J to reformat this section of comments, and your caret remains at the same location in the text that it had before. For example, suppose your caret were at the end of line 5 below: But much more conveniently, you can skip making a selection and just let the Editor infer the current section of comments for you. Previous to R2010b, if you wanted to reformat a section of comments as you edited, you first had to select the region that needed reformatting and then press Ctrl-J (or Shift-Fan-W on the Mac). In R2010b, we’ve made this feature easier and more powerful. The feature also includes automatic comment wrapping, which occurs as you type beyond the end of a line. In short, comment wrapping is a feature of the MATLAB Editor (accessible via the “Text” > “Wrap Comments” menu item) that allows you to go from ragged, messy comments: In the second part, we’ll cover more advanced maneuvers for the serious comment writer. In this first part, we’ll introduce comment wrapping and talk about how it’s now easier to use. In this two-part series, we’ll take a detailed dive into those improvements. In R2010b we made a series of improvements to the “comment wrapping” feature in the MATLAB Editor.
