Question

对于下面的代码，我想要输入值b和k，n次：

syms Q i w h2 h1 k

% n is number of layers for computation

n = input (' ')

for j = 1:n

k1 = input (' '); b1 = input (' ');

% up to... 

k(n) = input (' '); b(n) = input (' ');

% so that i want to use the various inputs of b and k to calculate Q.

Qi=( -b(i) * k(i) )*((h2-h1)/w)

Q=symsum(Qi, i, 1, 3)

Answer 1

在循环中，您可以提示输入并将其存储为k和b值数组

% Pre-allocate k and b arrays
k = zeros(1, n);
b = zeros(1, n);

for ind = 1:n
    % Prompt for the next k value
    k(ind) = input('');

    % Prompt for the next b value
    b(ind) = input('');
end

或者，您可以直接提示用户输入数组

k = input('Please enter an array for k in the form [k1, k2, k3]');
b = input('Please enter an array for b in the form [b1, b2, b3]');

使用这些数组，您可以为Q和k的每个值计算b

Q = (-b .* k)*((h2-h1)/w);

如何请求多次输入，n次
