Question

处理以下代码时，我得到Matrix错误必须同意错误。 E(m+1)=z/w;工作区虽然清楚地表明z和w的尺寸相同，但是1001x1001。

   l=[0:10000];
n=[0:1000];
g=1;
a=-0.5;
b=0.9;
for m=l
    xl=cos(2*pi*m*n/10000)';
    yl=ex22_1(xl,g,a,b);
    %multiplication of matrix with its transpose resolves SUMn(yl[n])^2
    z=yl*yl';
    w=xl*xl';
    E(m+1)=z/w;
end
printf(gcf,'-depsc2',['lti_crazy_function.eps']);
createFigure;
plot(1,10*log10(e),'.');
xlabel('Frequency (Hz)');
ylabel('Magnitude (dB)');
grid on;

任何帮助都将非常感谢，谢谢！

您可以通过将它们存储在3D矩阵中来创建“矩阵阵列”：

var autoprefixer = require('autoprefixer');
var postCSS = require('postcss');

function prefix(css, res, type, fullPath) {
    postCSS([autoprefixer]).process(css).then(function(result) {
        var css = result.css;
        var length = css.length;
        res.writeHead(200, {
            'Content-Length' : length,
            'Content-Type' : type
        });
        res.write(css);
        res.end();
    });
}

Matlab错误Matrix维度必须一致
