Now i would lige to assign 1/3 of the value in the 4th column to each of the nodenumbers in the 1st, 2nd and 3rd column. Thereafter i would like the sum of all values assigned to eachnode to be displayed besides the node in a 10x2 matrix. ...

Find the incidence matrix of a system of five equations in five variables. Create the following symbolic vectoreqscontaining five symbolic differential equations. syms y1(t) y2(t) y3(t) y4(t) y5(t) c1 c3 eqs = [diff(y1(t),t) == y2(t),... diff(y2(t),t) == c1*y1(t) ...
如果find函数返回Empty matrix: 0-by-1，则表示矩阵a中不存在与max相等的元素。这可能是由于以下几种原因：矩阵a中没有最大值。矩阵a中存在多个最大值，但它们不恰好等于max。计算最大值时出现了舍入误差，导致最大值与预期值略有不同。为了避免这种情况，可以先确定矩阵a的最大值，然后再查找等于...
I am extracting rows from matrix acc1, which have a first column value within a certain range . This range is defined by two values taken from a double, a. I am getting error messages for this and not sure why. q=acc1(acc1(:,1) > a(1,1) & ...
To find a noninteger value, use a tolerance value based on your data. Otherwise, the result is sometimes an empty matrix due to floating-point roundoff error. Get y = 0:0.1:1 y = 1×11 0 0.1000 0.2000 0.3000 0.4000 0.5000 0.6000 0.7000 0.8000 0.9000 1.0000 Get k = find(y==0.3...
If you can also compute the Hessian matrix and the HessianFcn option is set to 'objective' via optimoptions and the Algorithm option is 'trust-region-reflective', fun must return the Hessian value H(x), a symmetric matrix, in a third output argument. fun can give a sparse Hessian. See...
