??? Error using ==> classperf at 163 When class labels of the CP object is a cell array of strings and the classifier output is a numeric array, it must contain valid indices of the class labels or NaNs for inconclusive results. Error in ==> perf at 42 clas...
I'm really not good at this. "Array... Learn more about array indices must be positive integers or logical
Use the result as row indices to select entire rows of X. The code shown does not require that i is a scalar or even a vector. It also does not require that the values in i are currently integer values, but if they are not then there is the risk that there could be an indexing ...
I am using the decimate function y = decimate(x,r) and I need to know to which index in x the value y(i) corresponds. This is not explicitly addressed in the documentation. In the first example the number of points is k*r+1 and according to the code...
An array is a fundamental and widely used data structure in computer science that organizes elements of the same data type into a contiguous block of memory. The elements in an array are accessed using an index or a key, which represents their position within the array. The index usually sta...
The "colormap" is a list of colors. The colors are store in the "rgb-format", which means one value between 0 and 1 per red, green and blue channel. Therefore the color table has 3 columns.you
The randperm I have (R2010b) looks like this:[~,p] = sort(rand(1,n));So in the case that n = 2 (for example), rand(1,n) will generate a huge number of different streams, but the sort will project these down on to only two different permutations.You are right: The Mersenne-...
Suppose x takes on the values x = 1, 1.2, 1.4, ... , 5. Use MATLAB to compute the array Y that results from the function y = 7 sin(4x). Use MATLAB to determine how many elements are in the array Y and If ,B,C are noncoplanar vectors (that is A,B...
But when I call the Pardiso solver and I give him the addresses of the arrays, the arrays are absolutely the same! I'm stuck in this problem since a month and I'm out of ideas. I tried to resize the array to fit exactly the size of the matrix, I tried to preallocate a ...
