Delete rows from tableSyntax deleteRows(fptr,firstrow,nrows) Description deleteRows(fptr,firstrow,nrows) deletes rows from an ASCII or binary table. This function corresponds to the fits_delete_rows (ffdrow) function in the CFITSIO library C API. ...
Delete Cells The syntax for removing rows or columns of a cell array is consistent with other MATLAB arrays. Set the cells equal to a pair of empty square brackets. For instance, remove the second row ofC. C(2,:) = [] C=2×4 cell array{'one' } {[ 2]} {0x0 double} {0x0 do...

首先要先全部选择X中的数据。Objects里选择Matrix Rows,然后Select All。 To perform this preprocessing, select the matrix “X” in the “Data matrices in the workspace” group. Then, in the “Objects” group, select the “Matrix rows” option and press the button “Select All” to select all...
Finally, you can reorient a table so that the rows of the table become variables of an output table, using the rows2vars function. You also can modify table variables using the Variables Editor. Load Sample Data and Create Tables Load arrays of sample data from the patients MAT-file. ...
bp神经网络主要由三部分组成,分别是前向传播,反向传播,测试模型。其中前向传播主要是计算模型当前的预测结果,反向传播是对模型进行修正得到能达到预测效果的模型,测试模型是看我们最后通过反向传播得到的模型能否识别出我们想要的分类,好下面我来分别介绍他们的原理~ ...
