If one operand is a scalar and the other is not, then MATLAB implicitly expands the scalar to be the same size as the other operand. For example, you can compute the element-wise product of a scalar and a matrix. A = [1 2 3; 1 2 3] ...

matrix是array的分支，很多情况下matrix和array都是通用的 arraylist
Abrir en MATLAB Online I have a distributed array created using: ThemeCopy cal_data=distributed.zeros(1,2); I would like to convert the array to a matrix, to use the curve fitting toolbox: ThemeCopy xdata=zeros(1,2); xdata(:)=cal_data; I get the following error: The following err...

In MATLAB, this is accomplished with the + operator. Similar to matrix addition, matrix subtraction means to subtract term by term, so in mathematical terms, cij = aij –bij. This would also be accomplished using a nested for loop in most languages, or by using the – (minus) operator ...
mxArray*im = mxArrayCreatString(in);//传参 mxArray *out = mxArrayCreateDoubleMatrix(row,3,mxREAL);//row是文件行数,返回数据的行数也是这些 //调用matlab函数 mlxCalculateTrajectory(1,&out,1,&im);//因为路径里面存在中文字符,在Qt里面不可避免地出现了乱码,网上的方法都是针对Qt4之前的,而且有滥用...
