The arguments must correspond properly (after type promotion) with theĬonversion specifier, and are used in the order given. More flags, an optional minimum field width, and an optional precision. In between there may be (in this order) zero or EachĬonversion specification is introduced by the character %, and ends with aĬonversion specifier. Which results in fetching zero or more subsequent arguments. Unchanged to the output stream and conversion specifications, each of More directives: ordinary characters (not %), which are copied The format string is a character string, beginning and ending in its To write to the same line many times (to show a progress string, for You can also use the '\r' characterĪs an explicit carriage return (with no line feed). Line using multiple printf commands, including the '\n' when This seems odd, but allows you to assemble a In fact, it does produce the text, but it then ThatĬan lead to some confusing behavior if you do not know what to expect.įor example, the command printf('Hello') does not appear to It is important to point out that the printf function does notĪdd a newline (or carriage return) to the output by default. Note that this printf command is not vectorized! Each It isĪn error if there are not enough variables to satisfy the format The values of the variablesĪ_i are substituted into the output as required. Here format is the format string, which is a string thatĬontrols the format of the output. This, however, will cause c to become an int32 type, as opposed to a logical type.PRINTF Formated Output Function (C-Style) The other way to do this is simply force c(d) = 0, which uses the logical indexing mode of FreeMat (see the chapter on indexing for more details). To isolate this case, we can AND the two vectors, to find exactly those entries that appear as true in both a and b:Īt this point, we can modify the contents of c in two ways - the Boolean way is to AND \sim d with c, like so However, the XOR and OR operations differ on the fifth entry - the XOR would be false, since it is true if and only if exactly one of the two inputs is true. First, we create a pair of vectors to perform the XOR operation on: Suppose we want to calculate the exclusive-or (XOR) of two vectors of logical variables. Some simple examples of logical operators. Note that shortcut evaluation only works with scalar The first test returns false, and an attempt to evaluate the second expression Is not valid without shortcut evaluation (if p is an integer, for example, Not valid unless the prior test is successful. Shortcut evaluation is useful for doing a sequence of tests, each of which is Then if expr1 evaluates to true, then expr2 is not evaluated at all. Then if expr1 evaluates to false, then expr2 is not evaluated at all. The binary operators AND and OR can take scalar arguments as well as vector arguments, in which case, the scalar is operated on with each element of the vector.Īs of version 1.10, FreeMat supports shortcut evaluation. AND ( \
