Matlab Print Variable

Disp x displays the value of variable x without printing the variable name another way to display a variable is to type its name which displays a leading x before the value.

Matlab print variable. Starting in r2019b you can specify table variable names that are not valid matlab identifiers. But i m trying to sort variables from highest to lowest and i want to get matlab to print their corresponding variables rather than just giving me numbers. S converts pi to 3 141593e 00. For example to evaluate pi type pi matlab responds with ans 3 1416 pi is a built in matlab variable.

Such variable names can include spaces non ascii characters and can have any character as the leading character. Formatspec can be a character vector in single quotes or a string scalar. If you specify a conversion that does not fit the data such as a text conversion for a numeric value matlab overrides the specified conversion and uses e. The who command displays all the variable names you have used.

If a variable contains an empty array disp returns without displaying anything. Who matlab will execute the above statement and return the following result your variables are. Type of each variables. Optionally you can specify identifier flags field width precision and subtype operators between and the conversion character.

When you access such a variable name enclose it quotation marks. If a variable contains an empty array disp returns without displaying anything. Disp excludes the variable name from the output fprintf uses the formatting string on each element of the variable. I know the disp command shows the values without the variable name and the fprintf command allows you to print a string with variables.

Below are several examples of printing information from variables using fprintf. Create a table that stores data about a set of patients. A ans b c the whos command displays little more about the variables variables currently in memory. In the example above applying n to each element had the net effect of printing a row vector as if it were a column vector.

Try the following examples sin pi 4 2 log2 4 sqrt 9. Disp x displays the value of variable x without printing the variable name another way to display a variable is to type its name which displays a leading x before the value. A formatting operator starts with a percent sign and ends with a conversion character the conversion character is required. Notice the use of s to print a string and d to print an integer and f to print a number with a decimal a floating point number.

The preceding command is actually a request for matlab to print the value of this variable.
