Using a single subscript to refer to a particular element in an array is calledlinear indexing. If you try to refer to elements outside an array on the right side of an assignment statement, MATLAB throws an error. test = A(4,5) ...
Many MATLAB functions that start withisreturn logical arrays and are very useful for logical indexing. For example, you could replace all the NaN elements in an array with another value by using a combination ofisnan, logical indexing, and scalar expansion with one line of code. B(isnan(B)...
MATLAB Answers How do I create a symbolic integer in the Symbolic Math Toolbox? 1 답변 Array of symbolic functions with index but "same" variable name 1 답변 Which code of BVP4C replaces the code xSol(t) = simplify(xSol(t)) OR pretty([xSol(t);ySol(t)]) of DSOLVE ...
Array indexing multiple equationsThis is not a differential equationx4(i+1)=x4(i)-1/(J1+m2*l1^2)*((1/2*m1*l1+m2*l1)*cos(x3(i))*x2(i+1)-(1/2*m2*l1*l2*cos(x3(i)-x5(i)))*x6(i+1)-1/2*m1*l1*cos(x3(i))*x2(i)-(sigma1+sigma2)*x4(i)-(-sigma2-1/2*m2*l1...
To grow an array X, you can assign a value to X(end + 1). If you make this assignment in your MATLAB code, the code generator treats the dimension you grow as variable-size. For example, you can generate code for this code snippet: ... a = [1 2 3 4 5 6]; a(end + 1) ...
I’m first going to define my array z1. 我首先要定义我的数组z1。 And let’s put in a few elements in there– 1, 3, 5, 7, and 9, for example. 让我们把一些元素放进去,比如1,3,5,7和9。 I can then define a new array called z2, which is just z1 with one added to every...
Open in MATLAB Online To Matt H, If you want to fill the value with nan (or zero, just replace the nan with 0 in below code) when no member of the row matches, you could use this: ThemeCopy % This array has no element meet the % threshold in the third row. a = [10 13 ...
Index exceeds the number of array elements (1). Error in myODE>@(t,x)[x(1)*x(2)+0.5*x(1)^3+x(1)*x(2)^2;-x(2)-2*x(1)^2+x(1)^2*x(2)] (line 16) which is weird because this error message doesn't appear when I change nothing else but replace the initial conditions...
FYI in Fortran [ ] or (/ /) are used to create an array - I don't think you need this for the example. If this doesn't help try coding what you want in Matlab so it works, and post that here so that I, or others, can help. ...
