Getting Started Quiz Is the Below statement true or False? A variable is a way of holding data in a program. Variables have names and values. The value of the variable is the data that the variable holds. You can refer to the data by the variable's name. You can change the value of a variable by assigning it a new value (hence the name variable) Relative to the data triangle, information is In MATLAB a collection of data (say numbers or text values) in a single column or row is called a? In MATLAB the position in an array or vector are called?
In MATLAB a collection of data values (for example, numbers or text values) with both rows and columns (2 dimensional) is called ? In MATLAB, when working with an array, the application needs information in order to perform calculations. It needs to know which rows or columns to use if you don't want to work with the entire set. MATLAB uses what to tell the system which rows or columns to use? What are the four layers of the Data Analysis Triangle, from bottom to top? Referencing the Data Triangle, data is: In MATLAB a single data point is called?
In MATLAB the values in an array or vector are called? In MATLAB you can put arrays together to create new variables using coma and semicolons. Suppose you have two arrays: a = [ 10; 14; 6 ] and b = [ 1; 3; 6 ] Given you create a new variable called ab; ab = [ a ; b] How would the elements of the results be displayed?
The following table gives the counts of bacteria at two different beaches. The shaded portion of the table corresponds to the MATLAB variable called beachesWhich of the below scripts defines the variable beach1that contains the bacterial count for beach 1. . In MATLAB, the combination of using the hold onand hold off commands allows you to plot multiple lines on the same graph. The MATLAB subplot function allows you to arrange your graphs within a single figure. It tiles or places your graphs in a mosaic based on the following syntax. subplot(m, n, p) What does p stand for?
In MATLAB, the subplot commands allows you to display multiple graphs in the same figure. The MATLAB subplot function allows you to arrange your graphs within a single figure. It tiles or places your graphs in a mosaic based on the following syntax.
