使用 permute 函数，通过在第二个参数中指定维度顺序，将每一页上的行下标和列下标交换。M 的原始行现在是列，原始列现在是行。

str2sym(symstr) evaluates symstr the place symstr can be a string representing a symbolic expression. Enter symbolic expressions as strings only when studying expressions from textual content documents or when specifying numbers precisely. Otherwise, don't use strings for symbolic enter.

Expressions that include relational operators on arrays, for instance a > 0, are real only when each and every element in The end result is nonzero.

When you've got information to put right into a mobile array, generate the array utilizing the cell array building operator, .

Make a mobile array which contains quite a few temperature readings taken with a given date. Specify a day as a personality vector, and temperatures being an assortment of doubles. To store these pieces of information in the mobile array, enclose them in curly braces.

str2sym assumes the = operator represents an equation, not an assignment. Also, str2sym won't insert the variables contained in the string to the workspace.

Show this actions by examining a differential equation and First issue from a file. Resolve the equation with the affliction. For the reason that str2sym would not Consider y(t) inside the equation, the discover this info here output is reproducible.

Because the MATLAB® parser quickly converts all figures to double precision, maintain initial precision by entering significant figures and superior-precision numbers as strings. Instead of str2sym, enter integers employing sym and floating-point figures applying vpa due to the fact sym and vpa are faster.
