Otherwise, it is odd.Jul 10, 2020 · So, for MATLAB, the 1st statement being true is enough to execute everything within the if condition. Indeed, I have already solved my problem using the negative of ismember. I just would like to understand why using the first scenario would show every 'd' value. Apr 8, 2011 · MATLAB doesn't have conditional expressions, but in some situations you can get a similar effect by saying, e.g., var = cond*true_expr + (1-cond)*false_expr.Unlike C's conditional expression, this will of course always evaluate both true_expr and false_expr, and if cond happens not to be either 0 or 1 (note: false behaves like 0; true behaves like 1) you'll get crazy results. Description. r = rem (a,b) returns the remainder after division of a by b , where a is the dividend and b is the divisor. This function is often called the remainder operation, which can be expressed as r = a - b.*fix (a./b) . The rem function follows the convention that rem (a,0) is NaN.A linear index allows use of a single subscript to index into an array, such as A(k).MATLAB ® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right. For example, consider a 3-by-3 matrix. You can reference the A(2,2) …Description MATLAB evaluates the expressionand, if the evaluation yields a logical true or nonzero result, executes one or more MATLAB commands denoted here as statements.
