谢谢，函数bnb20的原型是：function [errmsg,Z,X,t,c,fail] = bnb20(fun,x0,xstat,xl,xu,a,b,aeq,beq,nonlc,setts,opts,varargin);我理解x0就是我在命令行里的[-1,-1];应该不会有问题啊有问题，x0=[-1;1];是个列向量恩，我对这个函数不是很了解啊，也没有用过的
Error: x must be a vector, not a rsplit/vfold_split object I am experiencing the above error when using tidyr::crossing() just after creativng a rsplit object using vfold_cv(). The error is intermittent, it happens sometimes. Others have been able to reproduce, sometimes. Example csv...
This low-drag and thrusting flight configuration resembles an open book, where the solar array is laid out flat in front of the vehicle. When Starlink satellites are orbit raising, they roll to a limited extent about the velocity vector for power generation, always keeping the cross sectional a...
prcomp(data) # Try to apply prcomp function # Error in colMeans(x, na.rm = TRUE) : 'x' must be numericUnfortunately, the “Error in colMeans(x, na.rm = TRUE) : ‘x’ must be numeric” is returned.The reason for this error message is that our data frame contains the column x1 ...
Hello, I want to creat a plot with two x axis (first one in the bottom and second one in the top) . I want to set the range of the seconde axis equal to a column array (x2) (the first point in the x xis = first element in x2). I write the following code; ...
s= xspectrogram(x,y)returns the cross-spectrogram of the signals specified byxandy. The input signals must be vectors with the same number of elements. Each column ofscontains an estimate of the short-term, time localized frequency content common toxandy. ...
If an eigenvector fails to converge, then the corresponding column of the global matrix Z contains the last approximation to the eigenvector, and the index of the eigenvector is returned in ifail. This identifies the first element of the local array Z. This subroutine computes the location ...
rowSums(iris_num[,1])# Row sums for one column# Error in rowSums(iris_num[, 1]) :# 'x' must be an array of at least two dimensions Example 2: Debugging the Error Message –‘x’ must be an array of at least two dimensions ...
The value for each node must be the same. This parameter is used for tests. Users are not allowed to enable it. Type: SUSET Value range: Boolean Default value: off enable_force_vector_engine Parameter description: Specifies whether to forcibly generate vectorized execution plans for a ...
If any of controlQubit1, controlQubit2, or targetQubit is a scalar, and at least one of the inputs is a vector, then MATLAB® expands the scalar to match the size of the vector input. The qubit indices in each element triplet of controlQubit1, controlQubit2, and targetQubit must no...
