Export Data to Excel File Using the writecell() Function in MATLAB. The writecell() function is used to …Please let me know if anything is unclear. My data is currently in excel in the format at the very top. So I'm thinking the easiest way would be to have a line that imports the data from excel, creates a matrix by using a word search through the row and then using that to take info from the appropriate column and create the matrix.While this works, I get tableFull.var2 in it's old shape, though I would like to have a (hoursTotal*nhi, 5) table, i.e., one separate table column for each array column. This would work if all elements were from the same data type: tableFull = array2table([dateTimeVector.', var1, var2])T2 = rows2vars (T1) reorients the rows of T1, so that they become variables in the output table T2. If rows2vars can concatenate the contents of the rows of T1, then the corresponding variables of T2 are arrays. Otherwise, the variables of T2 are cell arrays. The rows2vars function copies the names of the variables of T1 to a new variable of T2. Matlab Convert Table To Matrix. how to convert table to matrix?.
