If your goal is to operate on an array like this, then you would either use a test inside a loop (not my favorite in general) or you must use a vectorized test and assignment, perhaps like this: Dh = zeros(size(pinch); Dh(pinch > 0) = h.one - h.two; ...
Let's use the if...else... statement to complete a script that judges whether the input number is positive or negative for some display. 2.2循环语句 for循环结构中,需要设定一定的循环条件,Matlab根据设定的循环次数执行循环体内的命令。 for x = array commands end In the for loop structure, cert...
Adding the index of the cell array makes it almost 10x slower. Why? Also things such as "toc" inside the if statement have the same result. If they're inside the 'if' statement, shouldn't they be ignored until the 'if' statement is true... ...
Today I will introduce you to if statement, for statement, while statement. if语句 if statement if语句是条件语句,每一个条件语句都需要end关键词结束。 The if statement is a conditional statement, and each conditional statement needs to end with the end keyword. 下面举一个例子,生成一个随机数,如...
If size(A) and size(B) are the same, concatenate the arrays; otherwise, display a warning and return an empty array. Get if isequal(size(A),size(B)) C = [A; B]; else disp('A and B are not the same size.') C = []; end A and B are not the same size. Compare Char...
Thus if A is a matrix, then 3A and A−1 have a meaning, whereas, if A is an alpha-numeric array these statements have no meaning. Matlab supports matrix algebra, but also allows array operations. For example, an array of data might be a financial statement, and therefore, it might ...
g. 370 - 360 = 10, or 375 - 360 = 15). Is there any way to create a new array with the same size as the original that includes ALL longitude values (those between 30 and 360, and those I subtracted 360 from to get new values less than 30) using a for loop ...
Avoid adding a space after else within the elseif keyword (else if). The space creates a nested if statement that requires its own end keyword. Extended Capabilities expand all C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. HDL Code Generation Generate VHDL, Verilog...
Tips You can nest any number of if statements. Each if statement requires an end keyword. Avoid adding a space after else within the elseif keyword (else if). The space creates a nested if statement that requires its own end keyword. ...
B = all(A) tests along the first array dimension of A whose size does not equal 1, and determines if the elements are all nonzero or logical 1 (true). In practice, all is a natural extension of the logical AND operator. If A is a vector, then all(A) returns logical 1 (true) ...
