Cannot perform the operation: {positive constant} .* {real affine}. How to solve the multiplication of the matrix containing the value of `Inf`?

When I run my code, the following error appears. Hope to get your help. 错误使用 .* (line 173) Disciplined convex programming error: Cannot perform the operation: {positive constant} .* {real affine} 出错 CVXSolver (line 18) sum(sum(sum(cost.*adjacency))) <= u_cost; My main relevant code is as follows: %------CVX optimization------: cvx_begin variable adjacency(node_number, node_number, time_number) binary; maximize(sum(sum(sum(adjacency.*gain)))); subject to sum(sum(sum…
