Please I want to convert this array to an array. if I use str2double I obtain those starting 0.something as NAN. please help ' 0. 9' ' 0. 9' ' 1. 2' ' 1. 4' ' 1.14' ' 1.39' ' 1.42' ' 1.45' ' 1.46' ' 1.59' ' 2.28' ' 2.34' ' 2.43' ' 3.18' ' 3.35' ' 4.10' ...
It is unlikely that you would be able to improve on eval() speeds, as eval() runs at compiled speeds whereas anything you do at the MATLAB level is at interpreted speeds. To get something more robust but at compiled speeds you would need to move into a mex routine. OCDER on 20 Sep ...
Note that this would have newline characters between the parts. I am not sure that is what the poster wants.
To convert a cell array of character vectors to numbers, you can use the |str2double| function. This function is the simplest method. C = {'0.000000'; '10.000000'; '100000.000000'}; M = str2double(C) The |cell2mat| function converts a cell array of character vectors to a character array...
Another workaround that avoids the lossy duration type issues and doesn't need the messy struct solution for this particular case where the t0 variable is known to have a 0 seconds part. The crude answer is derived in two parts as seconds + nanoseconds...
Paul Romer, the 2018 Nobel Laureate in Economics, is a recent convert to Python. By his estimation, switching to open-source software in general, and Python in particular, brought greater integrity and accountability to his research. This was because all of the code could be shared and run ...

row vector to matrix 通过(end+1)指令编码出来的结果都是行向量的形式，如果要将其转化为矩阵时，我们可以将矩阵理解为多个规格相同的行向量进行累积，用代码表示为：The result encoded by the (end+1) instruction is in the form of a row vector. If we want to convert it into a matrix, we can...
