我喜欢在交互式命令窗口中使用MATLAB的shortEng符号: >> a = 123e-12; >> disp(a); 1.2300e-10 % Scientific notation. Urgh! >> format shortEng; >> disp(a); 123.0000e-012 % Engineering notation! :-D 但我想用fprintf: >> format shortEng; >> fprintf('%0.3e', a); 1.230 浏览3提问于2...
这里'%f'是格式说明符,用于固定小数点表示法 % '.0f'表示不显示小数部分,如果你希望保留小数位,可以调整'.'后的数字 % 例如,'%.2f'会保留两位小数 regularNumStr = num2str(sciNum, '%.0f'); % 显示结果 disp(['Scientific notation: ', num2str(sciNum)]); disp(['Regular number string: ', ...
%e Format as a floating point value in scientific notation. %g Format in the most compact form: %f or %e. \n Insert a new line in the output string. \t Insert a tab in the output string.The format function has the following forms used for numeric display −Format...

%e - Scientific notation (e.g. 1.2e+2) %e –科学计数符号(如:1.2e+2) %u - Unsigned decimal number %u –不带正负号的十进制数 %f - Floating-point number (local settings aware) %f – 浮点数据(本地设置) %F - Floating-point number (not local settings aware) %F –浮点数据(非本地设置)...
helps. However, integers that exceed 2^53 will be represented in scientific notation with "format long g". To get the full digits of those, you need to use sprintf() or fprintf() Image Analyst2011년 8월 7일 Yes it can help. Sometimes some sneak thr...
Unfortunately there is no way to do this. The scientific notation has no controls. You will need to set() TickLabel to a cell array of strings each entry of which is a string giving one of the labels, and you will have to text() the "x 10^-3" onto the axes ...
Numbers uses conventional decimal notation, with an optional decimal point and leading plus or minus sign, for numbers. Scientific notation uses the letter e to specify a power-of-ten scale factor. Imaginary numbers use either i or j as a suffix. Some examples of legal numbers are 3 -99 ...
%s: Represents a string value. %d or %i: Represents a decimal (integer) value. %f: Represents a floating-point value. %e or %E: Represents a floating-point value in scientific notation. %g or %G: Represents a floating-point value in either decimal or scientific notation. Example 1 – Prin...
I want to change the notation of the log y-axis: Here is an example code, which doesn't work: ThemeCopy y = [0.1 0.3 0.5 1]; figure(1), plot(y) yticks([0.1 0.5 1]) set(gca,'yscale','log') ax = gca; ax.YAxis.Exponent = 2 I found out that exponent notation doesn't ...
