Matlab 向量中的数据排列

我有以下向量：

以下是生成此向量的代码：

A = [11 115 167 44 51 5 6];
B = [100 1 1 87];
C = [2000 625];
D = [81 623 45 48 6 14 429 456 94];
E = [89];
F = [44 846 998 2035 498 4 68 4 1 89];

G = {A,B,C,D,E,F};

[max_val, idx] = max(cellfun(@numel, G)); % Find max sizes of vectors

% Create vector with zeros filling open matrix space
LeftIndented = zeros(idx,max_val);
for k = 1:numel(G), LeftIndented(k,1:numel(G{k})) = G{k}; end

我想要一个向量，其中包括：

右侧数据（左侧为零）

居中数据（用零包围）

（请注意，如果数据不能精确居中，则在左侧关闭一个向量空间即可）

---

如何实现这一点？

您可以用零填充每个向量：

A = [11 115 167 44 51 5 6];
B = [100 1 1 87];
C = [2000 625];
D = [81 623 45 48 6 14 429 456 94];
E = [89];
F = [44 846 998 2035 498 4 68 4 1 89];

G = {A,B,C,D,E,F};

[max_val, idx] = max(cellfun(@numel, G)); % Find max sizes of vectors

% Create vector with zeros filling open matrix space
LeftIndented = zeros(idx,max_val);
Centered = zeros(idx,max_val);
RightAligned = zeros(idx,max_val);
for k = 1:numel(G)
    LeftIndented(k,1:numel(G{k})) = G{k};
    l = length(G{k});
    padding = max_val - l;
    leftPadding = floor(padding / 2);
    Centered(k, :) = [zeros(1, leftPadding), G{k}, zeros(1, padding - leftPadding)];
    RightAligned(k, :) = [zeros(1, padding), G{k}];
end

这相当于

A = [11 115 167 44 51 5 6];
B = [100 1 1 87];
C = [2000 625];
D = [81 623 45 48 6 14 429 456 94];
E = [89];
F = [44 846 998 2035 498 4 68 4 1 89];

G = {A,B,C,D,E,F};

[max_val, idx] = max(cellfun(@numel, G)); % Find max sizes of vectors

% Create vector with zeros filling open matrix space
LeftIndented = zeros(idx,max_val);
Centered = zeros(idx,max_val);
RightAligned = zeros(idx,max_val);
for k = 1:numel(G)
    LeftIndented(k,1:numel(G{k})) = G{k};
    l = length(G{k});
    padding = max_val - l;
    leftPadding = floor(padding / 2);
    Centered(k, 1 + leftPadding:leftPadding + l) = G{k};
    RightAligned(k, 1 + padding:end) = G{k};
end

但在第二个代码中，向量值被写入零向量的正确位置。

使用以下方法的解决方案：

回答得很好，但你错过了正确的答案alignment@Irreducible是的，我错过了问题中的那部分。我现在加上去了。

A = [11 115 167 44 51 5 6];
B = [100 1 1 87];
C = [2000 625];
D = [81 623 45 48 6 14 429 456 94];
E = [89];
F = [44 846 998 2035 498 4 68 4 1 89];

G = {A,B,C,D,E,F};

data = [G{:}];
N = cellfun(@numel, G);
M = max(N);
idx = char((N.' >= (1:M))+32); 

Le = strjust(idx, 'left');
Ri = strjust(idx, 'right');
Ce = strjust(idx, 'center');

LeftAdjusted = zeros(M, N);
RightAdjusted = zeros(M, N);
Centered = zeros(M, N);

LeftAdjusted(Le.' ~= ' ') = data;
RightAdjusted(Ri.' ~= ' ') = data;
Centered(Ce.' ~= ' ') = data;

LeftAdjusted = LeftAdjusted.';
RightAdjusted = RightAdjusted.';
Centered = Centered.';
