Oct 08, 2017 · I want to let the program calculate the x value when y=0.5 and indicate this point (x,0.5) on the plot with dashed lines connecting to the two axes.. This produces the same output, but you can specify the multiple values you want to match using an array. So the following works too: >> ismember (a, [1 2 4 5]) ans = 1 1 1 1 0 0. Thus, you can do this with find : >> find (ismember (a, [1 2 4 5])) ans = 1 2 4 5. This lists the subscripts for all elements in a that are equal to 1, 2, 4 or 5.. The 'find' command only returns the indices of all the non-zero elements of a matrix have to compare the values in the array with the name of the images in the folder length Computers number of elements The first step of the anayltical approach is to find the critical values of the function `f(x,y)=x^3+y^3+3x^2-3y^2-8` This gives you the value (val) and the index (ind) of the max of the tensor. 2021. 11. 20. · Eigenvalues and Eigenvectors are properties of a square matrix. Let is an N*N matrix, X be a vector of size N*1 and be a scalar. Then the values X, satisfying the equation are eigenvectors and eigenvalues of matrix A respectively. Every eigenvalue corresponds to an eigenvector. Matlab allows the users to find eigenvalues and eigenvectors of. The find () function in MATLAB is used to find the indices and values of non-zero elements or the elements which satisfy a given condition. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition. It returns a vector that contains the linear indices. example. k = find (X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. example. k = find (X,n) returns the first n indices ....

Feb 01, 2013 · You can also use polyval(p,x) where p = [1 3 -2] in your example (the coeffients of your polynomial in descending order) and you will get the value of the polynomial at that point x (in your case, you would pass in 3).. . There is a bug in MATLAB 7.6 (R2008a) because of which a uitable is drawn with scroll bars even when its position height and width are set to the height and width reported by its Extent property under the Windows classic theme. This bug was fixed in R2008b, which is why the values of the extent property of the same uitable reported in R2008b are slightly larger. Learn more about cell, common values, matlab .

You can find the maximum point using the m a x and f i n d commands in Matlab: y m a x = m a x ( y); x m a x = x ( f i n d ( y == y m a x)); The other points do not exist in your data, i.e. there is probably no point that hits exactly the 20% line or the 50% line. For these you would need to interpolate. Share. Answers (2) Your code does not seem to have a call to interp2, so I'm not sure what might have gone wrong there. If you did not specify an extrapolation method explicitly, then the implicit method that MATLAB uses may have filled in NaN, depending on the interpolation method. For example, linear interpolation will fill NaN in the extrapolation.
